Excellent tutorial, I'm highly impressed. However I do have a question or two. First off, let me get this straight. Do you mix 2 tablespoons of water with 5-8 drops of glycerin and then add 5-8 drops of that mix to the silicon? Or do you put 2 tablespoons of water in the cup, add your silicon, and drop 5-8 drops of pure glycerin to that combination? And for my second question, you did a one piece mold. How on earth did you get the helmet out without tearing the mold or destroying the helmet?
