If there is one important material for evil geniuses, it's ballistic gel. This gel is the perfect copy of human flesh. It has the exact same weight, resistance, everything. Its easy to make, can be made in 45 minutes (counting refrigeration), and is great for testing guns. Ballistic gel is 100% gelatin, the same white stuff used for candy. Myth busters use this often for gun shoot tests. This isn't the myth busters recipe but an easier version.
