i dont know who came up with this jello thing but i dont see where it would benefit anything. that reminds me, i hate jello. i never liked eating it. ever.
sugar and yeast cause fermentation. gelatin is just not a part of that equation. it has no place in there.
if you want to mix up some variation on the thing experiment with champagne or brewers yeast and add a bit more sugar to the mix. then see what happens. it is possible that much more sugar would not be soluble in that amount of water but i do not know any specifics, that is for you to try out, and experiment with larger containers, gallon jugs and such.
stick to the basics and leave the jello shots for the little girls.
