Shake-N-Cast
From Wikipedia, the free encyclopedia
The Shake-N-Cast™ is a tire and footprint impression casting kit for police evidence collection produced by SIRCHIE Finger Print Labs., Inc.
The kit features a self-contained, pre-measured water capsule and dental stone casting material packaged in a single, heavy-duty plastic pouch. This simple-to-use kit eliminates all the mess and guess-work inherent with many other casting mediums. The dental stone material has the advantage that it last longer than just plaster, this is important as evidence has to be stored for a long time. The main ingredient is Plaster of Paris. The kit contains 2 lbs. (32 oz.) of dental stone and 14 fluid oz. of liquefier, factory-sealed in a tough plastic pouch. One kit is sufficient for casting a full-sized, adult shoe print. The Crime scene investigator simply has to apply pressure to break the water capsule, shake and knead the container for up to two minutes, cut off a corner of the pouch and pour it into the impression.
