Step 2: Mix the Knox
Unflavored gelatin can be found in the jello aisle of your local super market for about 1-3 dollars per box. For this tutorial, we only need 2 packets. (half the box).
There are many formulas for mixing the gelatin. Some are used for making cheap, single use appliances - including foamed latex style - and many other effects.
For this specific one, I only used water and gelatin. You can ad a teeny bit of glycerin to give the knox a more rubbery texture, if you want.
First, take a coffe cup of hot water and put it in the microwave for about a minute. While the water is in the microwave, pour the knox in the bowl. Pour a little water in an mix it thoroughly. Ad a little tiny bit of water at a time. The desired consistency of the gelatin is that of pancake batter.
Set the Gelatin aside for about a minute so it can JUST start to gel.
