What is the chemical reaction occurring here?
Vinegar + Bicarbonate Soda —> Carbonic Acid + Sodium Acetate
The carbonic acid is unstable though, so it breaks down into water and carbon dioxide forming the bubbles you see when the bicarb soda comes in contact with vinegar.

Variables to test
- Add bath crystals vs no bath crystals. Is the chemical reaction the same speed?
- Is baking soda the same as bicarbonate soda?
- Remove the food colouring from the recipe. Does the food colouring make any difference?
