CO2
I was thinking about a cheap/easy way to produce CO2. would a ice cream/soft drink mix produce a bigger amount of CO2 than just the soft drink alone?

Solubility of carbon dioxide in water is increased by low temperature and if you use ice cream with pop to make your CO2 there will be initial
evolution but less then the available CO2 will escape because at these lessened temperatures the amount of CO2 that can be solvated in water
increases.
Why not just go for baking soda and vinegar, that's the usual way.

Or, if you don't mind impurities, you can produce large amounts by burning something organic.
Never accept that which can be changed.

Most acid-carbonate/hydrogencarbonate reactions are very cheap, but theres one disadvantage; when you add the acid to the carbonate/hydrogencarbonate,
the mixture foams up quickly, so you would need a way of holding the liquid components back while allowing the CO2 to flow through.
You could, of course, just buy compressed CO2 in cylinders unless its unavailable/too expensive.

Yeast and sugar? Of course, you would have to find a use for the alcohol.

That would be pretty slow reaction though, wouldnt it?
Theres plenty of uses for the alcohol, even besides consumption

If you don’t waste acid, you could always heat a hydrogen carbonate (bicarbonate).

As a fast CO2 source I use a CO2 bike pump that uses 12g tubes (the ones that's used for pneumatic weapons). Although these don't last
long.. if only dry ice was cheap..
