Has anyone tryed this or heard of it
Mix together 2 packs of Jell-O (any flavor, since the end result is CO2
and nothing more) and 2 cups boiling water. Mix really well until it's all dissolved.
Add 1.5-2 cups sugar and mix well again.
Add 2 cups cold water and mix AGAIN. Make sure the sugar is dissolved and not just collected at the bottom.
Pour the mixture into the bottle and stick it in the fridge overnight, until it actually turns to Jell-O.
Once the Jell-O has hardened, add one cup room temp/lukewarm water and 1/2 tsp yeast. More yeast will produce more CO2
. I would suggest starting with 1/2 tsp. If you find that it's not enough, you can always open the bottle later and put in some more
