From Wikipedia, the free encyclopedia
A tippe top is a kind of top. When a tippe top is spun at a high angular velocity, its handle slowly tilts downwards more and more until it lifts the body of the top off the ground and points perfectly downward. As the top's spinning rate slows, it loses stability and eventually topples over. Explaining this phenomena requires use of very sophisticated physics. At first glance this could mistakenly be found to be a situation where the object gains energy.
