I use the "Jell-o Jiggler" mix listed on the pack, add a little sugar. A 64
oz juice bottle lasts well over a month.

What is the best recipe for DIY CO2? What is the longest you can go
without
changing the bottles? I have tried 2 different recipes and it seems the
less
sugar I use the better. I have a 2 cup sugar, 1/2 tsp yeast, 1/2 tsp
baking
soda recipe that does not seem to last as long as 3/4 cup sugar, 1 tsp
yeast, 1/2 tsp baking soda (both in 6 cups water). The first will only
last
about 2 weeks and the second about 3 weeks. Anyone else have a different/
better recipe? TIA
