This is a list of problems that have been solved by the fictional character MacGyver from the television series of the same name. Demonstrating resourcefulness in a hip, Renaissance man-like fashion, he employs his knowledge of science, technology and outdoorsmanship to resolve what are often life or death crises. Most often his ingenuity is put to the test as he faces imminent doom with little to no time or specialized resources with which to work (though at times it does seem he almost always has a Swiss Army knife and a roll of duct tape with him).
This list is incomplete; you can help by expanding it.
[edit] Episode list
Short summaries of all the episodes are in List of MacGyver episodes.
[edit] Pilot (1x01)
-
MacGyver destroys a laser array using binoculars and cigarettes. He lights three cigarettes from the lasers then puffs smoke (whilst coughing violently) to make the lasers visible. The episode states that the laser is a carbon dioxide laser. These operate at a wavelength of approximately 10 micrometers (far infrared) and are thus invisible no matter how much smoke is in the air. He then smashes the binoculars, removing a lens fragment to deflect a laser beam back to the emitter and destroy it. He also wipes his optics clean with bare fingers. Time index: 21:00.
-
MacGyver plugs a sulfuric acid leak with chocolate. He states that chocolate contains lactose and sucrose (Chemically C12H22O11), which are disaccharides. The acid reacts with the sugars to form elemental carbon and a thick gummy residue.
-
When MacGyver needs to move a large steel beam blocking his way, he cuts the end off a fire hose, ties a knot in the hose, and runs the hose under the beam. He then turns on the water, and the hydraulic pressure in the hose causes the beam to lift enough for him to shift it out of the way.
-
MacGyver creates a bomb to open a door using a gelatin cold capsule containing sodium metal, which he then places in a glass container filled with water. When the gelatin dissolves in the water, the sodium reacts violently with the water and causes an explosion which opens the barred door.
[edit] The Golden Triangle (1x02)
[edit] Thief of Budapest (1x03)
[edit] The Gauntlet (1x04)
[edit] The Heist (1x05)
[edit] Trumbo’s World (1x06)
-
In order to fix a piston for a water pump, MacGyver makes a stick welder out of a generator, some jumper cables, and two silver dollars, by running the DC current through the silver dollars to create heat and electrical discharge, with which he can weld the piston.
[edit] Last Stand (1x07)
-
In order to open a locked security van, MacGyver creates a "thermite" torch using magnesium filed from a racing cycle frame and rust held in a long tube and lit with a roadside signal flare. Side note: Thermite is made with finely ground rust (iron oxide) and aluminum powder, and is commonly lit with magnesium ribbon.
[edit] Hellfire (1x08)
-
MacGyver repairs a blown fuse using the aluminum wrapper of a stick of chewing gum to create new contacts to the damaged fuse terminals.
-
To carry several boxes of explosives leaking nitroglycerin across rocky terrain, MacGyver places the crates on a surface suspended by wagon springs and sand, both of which absorb shock from the terrain.

[edit] The Human Factor (2x01)
-
MacGyver builds a telescope using a newspaper, a magnifying lens, and a watch crystal (the crystal covering). He rolls the magnifying lens and the crystal into the newspaper, making a telescope. Due to a continuity error, it is not clear which lens he puts closer to his eye. He is also seen twisting the newspaper around the x-axis (i.e., the axis running the length of the tube), in order to get focus. Perhaps he put one lens in at an angle to the YZ plane (right handed) intentionally? Approximate time index: 14:00. Unverified.
-
In order to fake a handprint for electronic scanning, MacGyver applies distributed pressure to a thin layer of plaster dust covering the scanner, making it read the most recently scanned hand. He scrapes a plaster wall to get dust, then spreads it liberally over the entire scanner, where some of it sticks to the sweat of the previous user. He gently blows away the excess, covers the sensor plate with his jacket, and presses down lightly with his fingers. Category: Biometrics. Approximate time index: 17:15. Unverified.
-
MacGyver needs to destroy several laser emitters blocking a hallway, so he sets up a mirror to reflect the lasers at each other. The lasers come from the ceiling and cross diagonally at equal angles from vertical. MacGyver slides a mirror (pushed on a cleaning cart) underneath the lasers so that the lasers reflect back on each other and destroy the emitters. Approximate time index: 25:30.
-
As laser-wielding robots hone in on his body heat, MacGyver creates a fake heat signature by using magnets wrapped in burning paper. He opens several telephone handsets to get the magnets, and finds paper and matches in the science lab he is in. Once aflame, he throws one piece of burning paper, with a magnet wrapped inside, at each robot. The magnets stick to the metal of the robots. With each robot "tagged," they home in on each other and destroy one another. Approximate time index: 33:00. Unverified. Magnets would likely have been strong enough. (It should be mentioned that the robots would also have a heat-signature, potentially within the same range as a human—however, it is quite likely that heat-producing components within the robots themselves would have been shielded in some way, such that a burning object on the robot's external surface would have made them appear noticeably warmer).
[edit] The Eraser (2x02)
-
MacGyver repairs a post mix soda gun by bleeding off some built-up CO2 that has caused a valve to stick. He takes off the button panel of the soda gun, removes the troubled valve spindle (both with his Swiss Army knife) and inserts a miniature pirate's sword from a plate of olives. Using the sword, he opens the valve to the CO2 line fully, and draws out the sword which lets it close naturally. Unverified. Terminology source. Approximate time: 9:30.
-
In order to bypass an electronic door lock, MacGyver shorts out the circuitry. He detaches the main circuit board from the door, which is on the back of a metal plate. Using a cut power cable from a nearby lamp, he applies electricity from the wall to two of the main points on the circuit board. These points are apparently wired to a switch on the inside of the door lock which is designed to pass a current through them when the switch is pressed. The resulting short circuit causes the lock to open. Unverified. Approximate time: 15:45.
-
When he needs to remotely control a car's door locks, MacGyver connects the car's mobile phone to its onboard computer's signal lines for the door locks. Using his knife to open the back of the phone, he identifies the contacts where power is routed when the phone is taken off the hook. He opens a tube of wires and identifies, presumably based on color, the two wires which control the computer's locking circuitry. He wraps one wire around each contact, reassembles the device, and waits at a nearby phone booth. When the car's owner gets in, he calls the phone and pretends to order a pizza. The doors lock when the owner puts the phone down. The doors unlock when MacGyver approaches the car and signals to pick up the phone. Unverified (researchers should know this episode aired Sept 29, 1986). Approximate time: 25:00.
[edit] Twice Stung (2x03)
-
With his friend dying of carbon monoxide poisoning, MacGyver breaks through his friend's apartment door by tying a fire hose to the door handle and an elevator handrail, then sending the elevator down. He cuts the fire hose with his Swiss army knife, ties the nozzle end to the door, the other end to the hand rail, and lays the hose very flat against the ground so the elevator's doors won't close on it. When the elevator goes down, it pulls enough of the door with it that MacGyver can reach in and unlock the deadbolt and chain door lock. Unverified (can that knife cut that hose?) Approximate time: 5:30. Opinion of a former building engineer. Yes a common pocket knife could cut a fire hose. Today they are made of nylon wrapped around a rubber hose because of the water pressure. Knowing how many of these rest forever, rotting in the wall cabinets, one could cut it with a spoon too. No way will any elevator in proper working order move with any door not in closed position. (However, anyone who has pressed the light switch in their refrigerator to verify that the lights do, in fact, go out when the door is closed will know how to defeat such measures, especially on a 1986-era elevator.)
-
With two hostile men breaking into his friend's house, MacGyver stuns the intruders with a flash from a photoflood bulb, allowing him and his friend to escape. He takes the battery out of a normal, high power flashlight and connects one of the wires from the flood light power cord to it. The other wire he cuts in the middle, and strips both new ends. One end he attaches to the open terminal on the battery, and then he lays both ends near each other on the ground. He folds two matchbooks into triangles an inch high or so, and lays them near each exposed wire. He rests a metal letter opener on top of the two matchbooks. When the intruders step on the letter opener accidentally, the circuit is closed, and the lights flash. Unverified (battery power? Or did he connect the battery to the trigger pins?). Approximate time: 32:00.
[edit] The Wish Child (2x04)
-
MacGyver lights a fuse without a match by concentrating sunlight on the fuse with his watch crystal. He removes the crystal with his Swiss army knife and holds it so a fine point of light is focused at the fuse's end. Unverified. Approximate time: 13:00.
-
To scale a wall, MacGyver converts an umbrella into a grappling hook. First he pulls down a clothesline and cuts it, to get rope. Then he cuts away the fabric of the umbrella so only the metal spokes are left. He ties the rope onto the handle of the umbrella and throws it over the wall, where it catches on some pipes on the other side. It can be noticed that realistically this would not work, as the spokes on most umbrellas reverse themselves inside out if pressure is put on them, and therefore wouldn't be able to support a person's weight. Unverified. Approximate time: 27:45.
-
When blocked by a heavy door with a strong lock, MacGyver destroys the lock by igniting gunpowder inside of it. He steals the gun from a henchman and empties it of cartridges. He opens each cartridge and pours out the gunpowder into a small piece of cloth torn from his clothes. He stuffs the wrapped up powder into the lock, and puts one cartridge in after it, with the primer end sticking out a bit to act as a fuse. He hits the primer with the butt of the gun, exploding the gunpowder and opening the door. Approximate time: 42:15. Note that this trick was first used on film in 1942 in the eleventh episode of the Columbia serial The Phantom, starring Tom Tyler. The Phantom escapes from the prison of the villainous Tartar using the same technique.
[edit] Final Approach (2x05)
-
To scare away a mountain lion, MacGyver creates a basic waterfall from a small stream. He uses a hollow half-pipe shaped log to guide the water flow and removes rocks from its path. Approximate time: 24:15.
-
MacGyver builds a stethoscope out of a pair of headphones and some rubber tubing. He gets a pair of 2 ft (.6 m) rubber tubes from a cockpit pressure gauge. He disassembles the headphones, which operate on air pressure rather than electrical current. Using just one ear piece, he takes out the existing rubber tubing, and replaces it with the loose tubing from the plane. This essentially creates a microphone out of the ear piece, and he can now listen from the opposite ends of the tubing. Unverified. Approximate time: 31:30.
-
In a particularly elaborate stunt, MacGyver builds a mud runway for a plane. This allows the plane, which has a punctured front tire, to takeoff, after replacing the wheel with a log that has a v-shape chiseled out on the inside and a smoothed half-circle outside. (The other two wheels ride on solid ground.) First the runway area is cleared of debris, then a 1 ft (.3 m) trench is dug. The mud is filled in from a nearby river, carried in campers' backpacks. In order to align the runway, MacGyver builds a theodolite, a device used to sight straight lines. The theodolite is built from relatively straight tree branches and uses earrings as sight guides. The runway is 300 yards (274 m) long, and the plane is a five-passenger, single engine Cessna. To land the plane, he has an airport lay down foam. (Saying that the trench was 8 inches wide, the trench would require ~22 cubic yards of mud. This would probably take several days to do.) Approximate time: 35:00.
[edit] Jack of Lies (2x06)
-
In order to stop a pursuing Jeep, MacGyver builds a bomb out of a fire extinguisher. He is in a plane that is being chased down a runway by several Jeeps. To stop one of them, he tapes two metal hooks to the outside of the extinguisher and removes the nozzle assembly. Then he launches it out of the plane with elastic ropes that cover the door. When the Jeep drives over the extinguisher, the hooks pierce the cylinder and it explodes. Unverified. Approximate time: 16:00.
-
In setting a trap, MacGyver recharges a lead-acid battery with wine. He unseals the battery and pours wine in, which replaces the missing distilled water. This gives the battery a small charge which is what he needs for his trap. Unverified. (Possibly misunderstood.) Approximate time: 38:00.
-
In part 2 of MacGyver's trap, he ensnares the bad guys with a tarp. A floor switch is made from a board on a spring, which, when stepped on, closes a circuit. The circuit runs through the battery and to a starter motor on a prop plane. The starter motor turns the propeller, which is tied to a rope that hoists up the tarp. Unverified (battery power). Approximate time: 47:30.
[edit] The Road Not Taken (2x07)
-
To stun soldiers pursuing him, MacGyver burns a string dipped in kerosene attached to a tin can. The resulting flame is bright enough to look like a fuse for a bomb, and the can is filled with animal fat which resembles an explosive. Approximate time: 15:00.
-
When he needs to throw off some pursuers in the jungle, MacGyver builds a tree-based catapult to throw stones, and puts a light-based fuse on it. First he pulls four flimsy trees together and bends them down to the ground. He routes them under a solid tree branch and ties them together with a thin vine. Then he sets down his friend's rosary to refract sunlight onto the thin vine, creating a fuse. He stakes the thin vine into the ground with a good knot on a pointed stick, and attaches the pockets from his jacket (filled with rocks) to the tree trunks. Approximate time: 23:30.
-
MacGyver creates a rocket-propelled flare out of bamboo, fertilizer, matches, a strip of cloth, a small tin can, a thin metal rod, a funnel, and a wooden spoon. The fertilizer has nitrates, which is the explosive. He packs the fertilizer in the bottom of the bamboo, then the matches, then the tin can which is itself packed with the cloth with a strip hanging out. He ties the spoon onto the side of the rocket with the metal rod used as a guide within the bamboo tube. The funnel is attached to the top of the rocket, to contain the explosion. The strip of cloth serves as the fuse, and then matches as the igniter. MacGyver sets the entire apparatus in a fireplace, where he lights the fuse and lets the rocket take off. *This is basically a potato gun, a few differences aside: Instead of a potato he uses the crudely fashioned rocket described above for ammo; instead of BBQ igniters he uses match heads (which typically contain red and white phosphorous-both somewhat explosive); instead of the standard propellant (typically propane) he apparently felt safe using a similar ANFO (Ammonium Nitrate/Fuel Oil)(Possibly incorrect: ammonium nitrate is not nearly as volatile with out fuel oil or gasoline...niether of which are mentioned) compound to that used by Timothy McVeigh in the Oklahoma City bombing. Like so many other situations calling for a quick torch, he uses a (suspiciously) handy road flare to set the "potato" gun off.* Approximate time: 43:30.
[edit] Eagles (2x08)
-
MacGyver is trying to help an eagle shot by the crossbow of a hunter. After he removes the arrow from the wing, he splints the wing with the arrow and some rags. The splint is essentially the same as any other, with the arrow serving as the inflexible component and the rags to tie it together. Approximate time: 11:30.
-
MacGyver destroys a building with a propane tank, a grindstone, and some ball bearings. He lets the gas from the tank loose and switches on the grindstone. From outside, he shoots the ball bearings into the building at the grindstone. Although he doesn't hit the grindstone, the bad guy he is after shoots a crossbow into the building, and does hit the grind stone. A spark ignites the gas, and the building is flattened. Approximate time: 35:45. Natural, propane gas as well as gasoline alcohol and paint thinner will ignite and holds the potential to violently explode, if the mixture is correct. A low gas to air mix will result in more of a rolling fire ball, which is what special effects probably used for the shot. The next level of mix will violently explode and will flatten a house. Too much gas will not explode as in a "flooded" automobile motor. Two good sources of remote ignition exist in some homes. First is the pilot light in gas appliances, second is that electric motors while running will spark around the electrical contact point with the armature.
-
In order to launch the above mentioned ball bearings at a high enough rate of speed to build a spark, MacGyver must build a slingshot. He uses a bicycle and some old tubing to do it. He pulls the handlebar grips off the bike and covers the exposed metal on each side with parts of the tubing. Then he replaces the grips over that tubing, giving him a tight but elastic portion of tubing. That's his slingshot. Approximate time: 36:15.
-
Despite MacGyver's best efforts, an eagle he is trying to save doesn't make it, and its young are at stake. After hang gliding to the nest on top of a butte in Monument Valley, Utah, MacGyver brings the eggs back to the house where this episode takes place. To give the young a chance, he builds an incubator with padding from a chair and vegetable oil. As MacGyver puts it, "the oil combines with the fibers in the padding to create a low level spontaneous combustion," generating heat. Approximate time: 45:15.
[edit] Silent World (2x09)
-
MacGyver builds a time-delayed device to pull a switch out of water using plastic bags, sticks, and fishing line. He fills the two bags with equal amounts of water, and ties them to a straight stick. He balances the stick on a fulcrum made of two other sticks, and then attaches a fishing line from one water bag to the switch. He pokes a hole in that bag, letting the water slowly drain out, eventually making the whole apparatus tilt and pull the switch. Approximate time: 44:00. Plausible.
[edit] Three For the Road (2x10)
-
MacGyver stops goons chasing his convertible by flipping the top of the car onto their windshield. The chase starts with the convertible's top down, and MacGyver unscrews it and cuts it free from the binding fabric. The driver of the convertible then pushes the button to put the top up, which releases the whole assembly. It flies onto the chase car, blinding the pursuers. Approximate time: 21:00. Unverified.
-
MacGyver fixes a broken fuel line with a ball point pen. The fuel line has a hole in it, so he cuts out the section with the hole completely. He then joins the two loose ends by sliding them over a portion of a disassembled ball point pen so they form a seal. The fuel flows through the hollow pen housing. Approximate time: 23:00.
-
MacGyver builds a mortar out of a muffler, a small amount of gas, stuffing from a seat cushion, and a steering wheel knob to stop pursuers. He bends the end of the muffler, to contain the explosion, and stuffs seat cushion material into the bent end. He then pours gas on top of that, and finally packs in the steering wheel knob, which serves as the projectile. He pokes a hole in the bend end of the muffler and stuffs in a short length of cushion material, to provide a fuse. He lights it, aims, and shoots the knob at a chasing car. Approximate time: 27:30. Unverified.
-
To stun intruders, MacGyver rigs a circuit to blast a car horn when a door is opened. He connects a car battery to a car horn, with a metallic door handle acting as the switch. When the door is opened, the circuit is closed, the horn sounds, and the intruders are stunned. Approximate time: 39:00. Unverified.
[edit] Phoenix Under Siege (2x11)
-
MacGyver moves a New York lock from the opposite side of a door with an electromagnet. To build the magnet, he uses two 12-volt batteries as his power source, a sink faucet as the metal rod, and some copper cabling to wind around the faucet. He connects everything, and slides the lock out of place. Approximate time: 33:30. Unverified.
[edit] Family Matter (2x12)
-
MacGyver busts open a steel window covering with some rope and a donkey engine. A donkey engine is a device used in the logging industry to move fallen trees. Part of the engine includes a belt that goes around a cylinder, which MacGyver replaces with a rope. He ties the opposite end of the rope to a steel bar that he slits between the crossbars on the window covering. Through the rope, at the end next to the engine, he splices a thin metal cable which he attaches to the ignition switch. That lets him wait next to the window, and when he's ready, turn on the engine by tugging the rope. Approximate time: 32:00. Unverified (would it be plausible to find a donkey engine still in use?).
-
To throw his opponents off balance, MacGyver builds bombs out of swamp gas, bamboo shoots, and mud. Because a bamboo shoot is hollow but not porous, it is well suited to hold gas. Swamp gas is mostly methane, which is lighter than air and thus rises out of swamps naturally. So MacGyver cuts several bamboo shoots, each just past the natural solid disc that is in bamboo every few feet. The disc, patched with mud, makes one solid end, and the other open end he puts just under the surface of the swamp water. He lets the gas build up inside the shoot for a little while, then caps it off with a wad of mud and a leaf. When he's ready to detonate the bombs, he lights the leaf, and eventually the gas explodes. Approximate time: 39:00. Unverified.
[edit] Soft Touch (2x13)
-
MacGyver uses a road flare to follow a van without being spotted. As the van gets moving, MacGyver pulls a road flare out of the back of his jeep and throws it onto the roof of the van, into an equipment rack. The smoke trail from the flare is enough to allow MacGyver to follow it without needing to maintain line of sight. Approximate time: 32:00.
-
MacGyver breaks a padlock with magnesium alloy fragments, an iron pipe, some cloth, and a match. First he rolls up the cloth to fit snugly into the pipe, and pushes it down a few inches to make a stop. He gets the magnesium from the spokes of a wheel-chair's lower wheel and stuffs it on top of the cloth, and then covers that with another cloth. He wedges the pipe into the end of the padlock and lights the cloth on fire, causing the iron to heat up and expand. As it expands, it weakens and finally breaks the lock. Approximate time: 39:15.
[edit] Birth Day (2x14)
-
MacGyver creates a distress beacon out of a mast bag, marine signal flags, helium gas, and water. The point is to get help from someone a ways away, so he needs to send the flags their way. He first soaks the mast bag in water to make its surface less porous, so that it will retain helium gas. He then fills the bag with gas and seals it with a string. Dangling from the string, he attaches the signal flags - four in total, one for each letter of the word help. Approximate time: 41:30.
[edit] Pirates (2x15)
-
In a rare unsuccessful MacGyverism, MacGyver fails to blow open a hatch with a bilge pump, a hose, and a dock buoy. MacGyver is stuck in the bilge of a ship that is taking on water. He has the idea that he can blow open the locked hatch (locked by the bad guys, naturally) by overfilling a buoy with water until it explodes. He pokes a hole in the buoy, inserts a tube, connects the end to the bilge pump, and fastens the buoy to the hatch with an angle brace. Unfortunately the buoy tears instead of exploding, causing the water to spill out and defeating the MacGyverism. MacGyver escapes from the predicament by finding a nearby tank of compressed gas and knocking open the valve, sending it shooting up through the hatch, blasting it open. Approximate time: 30:00.
-
MacGyver safely detonates a land mine with a piece of string. The land mine is triggered by a rope, which when pulled on, arms it. When the rope is let loose, the mine goes off. The idea is that as you are walking, you trip over the wire, setting off the land mine. MacGyver catches himself as he arms the land mine, and then ties a piece of string to the rope. He holds the rope taut, walks away from it, and finally lets it go off from a safe distance. *Note (From a Combat Engineer): It is a common misconception that anti-personnel mines are armed and fired in this manner. In reality, the mine would detonate when a predetermined amount of pressure (generally around 10 lbs.) was applied to the top of the mine, not via a two phase process. Approximate time: 39:00.
[edit] Out in the Cold (2x16)
-
MacGyver is trapped in an avalanche while skiing. He manages to signal a rescue team from beneath the snow with a ski pole and parts of his ski suit. He pulls the grip and point off of his ski pole, giving him a 5-foot long hollow tube. He tears off some cloth from his ski suit in roughly a square shape, and then a long, narrow piece and his zipper pull. He ties the square into a parachute with the narrow piece and attaches the zipper pull to give it a weight. He feeds the whole bundle into his pole and blows it out the other end, which he has poked through the surface of the snow. A member of the nearby rescue team sees the parachute and saves him. Approximate time: 18:00. Most avalanche survivors tell of being immobilized by the snow once it has stopped its motion. Experts describe the powder snow falling in an avalanche as being like a dry moving concrete that once it stopped moving immobilizes victims. His escape is unlikely unless he has room to move his arms. If that is the case then he could dig himself free enough for rescuers to find him.
-
Using parts of a microscope and a drop of water, MacGyver is able to read microfilm which some bad guys are after. He uses the light from the microscope to backlight the film, and the drop of water is his magnifying glass. The viewing head on this microscope is broken and not used. Approximate time: 35:00.
[edit] Dalton, Jack of Spies (2x17)
-
While being pursued by dirty CIA operatives at a strip club, MacGyver loads a confetti cannon with make-up powder and fires it at them as they enter a door, thus blinding the enemies with powder. Unverified. Approximate time: 26:23
-
MacGyver is trapped in the back of a garbage truck and his captors have activated the sledge (compactor) to crush him. Plan A is to use boards found in the trash as braces to hold the sledge back, but the boards are crushed. Plan B is to use a bent piece of metal to hook the levers outside the truck, pull them, and stop the sledge. The MacGyverism almost works: instead of stopping the sledge, MacGyver opens the rear door. This allows him and his friends to go to plan C: Jump. Approximate time: 42:00.
[edit] Partners (2x18)
- Trapped in the driver's seat of a car with bazookas pointed at him, MacGyver needs to get out of the car and disable the bad guys all in one move. He removes his shoelaces and ties a lasso, using it to rope the gas pedal. He slips a paper clip onto the lace, secures it in a monkey wrench, and manipulates the wrench so it is braced between the floor and the brake pedal. This situates the lace so that when pulled on, it will pull down the gas pedal. Finally he routes the lace around the steering wheel on ties it to the door handle. The result is that when he gets out of the car, it will lurch forward and crash into the bad guys. Approximate time: 18:00.
- MacGyver needs to blow open a locked truck trailer door. He builds a bomb out of an oil can, a pair of pantyhose, an old exhaust pipe, and an old battery. He soaks the pantyhose in oil, which serves as the fuse. He threads that through the exhaust pipe, at the end of which he has packed shavings from the aluminum can. The idea is that "the ferrous oxide in the aluminum shavings should generate enough heat to explode the battery." It works. Approximate time: 41:00. Ferrous oxide is made of iron, not aluminum. However, ferrous oxide, or rust, may be inside an old exhaust pipe, thus creating a thermite reaction, which nevertheless cannot be ignited using oil. The typical wet cell car battery will discharge hydrogen gas which will ignite and explode the battery.
[edit] Bushmaster (2x19)
- MacGyver creates a diversion with a rifle, a rock, some newspaper, a string, and a match. He hangs the rifle in a tree and ties the string around the rock and the trigger. The way it is tied, when the string is cut, the rifle will fire. He puts the newspaper next to the string and lights it, creating a fuse. Approximate time: 4:00.
- To break open a lock, MacGyver exposes it to Freon gas. The Freon comes from the back of a refrigerator, in a crimped pipe. MacGyver opens the pipe, lets the Freon freeze the lock, and is able to break it with a hard push. Approximate time: 34:00. Whereas the temperature of R-12 from the open line is –30 degrees Fahrenheit, there is not sufficient quantity to last long enough to freeze metal to a point where it becomes brittle. It will give skin very nasty frostbite. This scenario is not very likely. Also, simply crimping the lines would not be likely to make a seal that would hold enough pressure to keep Freon from escaping.
- With an old, bullet-ridden Jeep his only means of escape, MacGyver must patch up the Jeep's radiator to get it working again. Remarkably, he does the job with nothing but water and egg whites. First he dumps some water in the radiator and jump-starts the Jeep, causing the water to heat up. A few minutes later, he dumps in the egg whites, which the water cooks. Once cooked, the egg whites naturally plug the holes in the radiator, making the Jeep temporarily usable. (This was confirmed as plausible in an episode of The Discovery Channel's "Mythbusters") Approximate time: 40:00.
- MacGyver is being tailed by goons in a car faster than his rail-bound vehicle. He builds a giant, road busting bomb out of gasoline, several types of ammunition, and tear gas. To light it, he rolls up some paper and strikes a piece of metal on the rail he is riding on, causing a spark. Approximate time: 46:00.
[edit] Friends (2x20)
- This episode looks back at some of MacGyver's previous feats and contains no new MacGyverisms.
[edit] D.O.A.: MacGyver (2x21)
- MacGyver creates a thick fog out of ship hull cleaner and ammonia. Ship hull cleaner contains muriatic acid, which is used to clean algae off ships. It creates a fog when combined with ammonia. MacGyver fills two buckets, one with each chemical, and spreads liberally on the floor. Approximate time: 8:00.
[edit] For Love or Money (2x22)
- MacGyver distracts some goons by creating a smoke cloud out of carbon black (commonly known as soot), a helium tank, a latex lab glove, duct tape, and his pocket knife. The powder is stuffed in the glove, the glove has a slit and is inflated with the helium gas. MacGyver duct tapes the glove to the top and bottom of a food serving tray so that when it is opened, the glove will burst and the powder will be released. Approximate time: 17:00.
- MacGyver creates a bomb out of nitroglycerine tablets and alcohol. He finds the nitroglycerine in a medical lab, where they are used to help weak hearts. He crushes the tablets and mixes in the alcohol, creating a paste. He folds the paste up in two flat napkins and duct tapes the ends. To detonate the bomb, MacGyver throws a non-descript blunt object at it. Approximate time: 18:45.
- MacGyver protects his car with electricity using baling wire to zap soldiers that are trying to force him out of the vehicle. He runs the baling wire from the ignition coil to the frame of the car, and when the two soldiers put their hands on the door handles, he pushes the wire tightly against the frame, shocking them. Approximate time: 32:00. This can work; An ignition coil is used in a automobile's ignition system to transform the (usually) 12 volts of the vehicle's electrical system to the tens of thousands of volts needed to jump the gap at the spark plugs to ignite the air/fuel mixture. When current flows through the primary winding, it creates a magnetic field. When that current is cut, the magnetic field can collapse, creating the necessary voltage in the secondary winding — if there's a place for the released energy to go. For MacGyver's plan to succeed, the coil's charging circuit's (-) pole must be earthed — connected to the ground beneath the car — without continuity with the body or chassis, and the coil's spark plug connection must be connected to the body/chassis. If the coil is charged but not drawing current when the soldiers touch the car, they'll be zapped with the high voltage current as they complete the circuit from the earth to the body. Once the coil has discharged, it can be recharged as, MacGyver could repeatedly open and close the primary circuit to keep shocking the soldiers until the battery ran dead.

MacGyver plays back an old phonographic record on a black cylinder using a piece of paper and a safety pin that he rips from a Misha breast pin. He rolls the sheet of paper into a cone and puts a safety pin on the tip. MacGyver places the tip of the safety pin on the black cylinder and rotates it in order to listen to the contents. Plausible, novelty item gramophones using paper cones for the amplification and wall tacks for the needle are available from many manufacturers.

In order to save Pete Thornton's life attacked by an enemy agent with extremely poisonous bitter almond odor prussic acid (hydrogen cyanide), MacGyver uses sodium thiosulfate as antidote drink from a near photo shop's printing machine that uses it as a photographic fixing agent.
- MacGyver once freed himself from handcuff captivity with a paperclip, when he was free from the handcuffs, he couldn't use the paperclip to open the door of the room he is trapped in, so he used the handcuffs to pick the lock the same way he did to free himself from the handcuffs.
