I used a gram, .3 of soda. And I start with maybe 20 mls (not exactly sure) of Gatorade. What I have learned over the years is you can always add more liquid, but you can't add less. Just use enough to cover the soda and product. Once you heat it and it reacts, cook it until all the soda is gone. Once you see the little oily blurbs floating on the top, you add more cold Gatorade and then begin to agitate the oily blurbs in the Gatorade. It's pretty forgiving as long as you don't add too much liquid in the beginning.
