sugar, yeast and warm water will do. im pretty sure all yeast is the same anyway. brewers yeast i believe is the common choice

you forgot a small bit of bicarbonate of soda. It keeps it more regulated and constant.

Jello would help too. add plenty and shake. This slows down the rate of consumption of the sugar, making it lastt longer?
