Long acting CO2 generation?
Combining sodium bicarb with most acids goes to completion within minutes. Can anything be done to slow this reaction down?
Short of adding yeast to sugar, are there any chemicals that can be combined to produce a slow smouldering production of CO2 over many hours?

I don’t have an exact answer, but my limited chemistry knowledge says that:
1. Weak acids react slower than the strong ones. Maybe some very weak acid + baking soda will react long enough?
2. Speed of the reaction depends on the temperature. Cooling down the medium will result in slower reaction
Also, another approach could be if you have some equipment to slowly add acid to the baking soda
