In this video we are going to turn milk into a hard plastic, nearly a strong stone. First we need one warm cup of milk. We are goinig to heat it in a microwave for 30 seconds and then measure of the corrected milk. The second item we need is one spoon of vinegar. Basically, for every cup of milk you use, add 1 tablespoon of vinegar and you can make a much larger batch. Mix it together and strain out the curds that form. Once you dry it you can mold it into any shape you desire, but let it dry for a couple days first!
