This demonstration actually works better when the mothballs are added to a clear soda drink (e.g. 7-Up).
The mothballs by themselves are just a little bit denser than the liquid, so they sink to the bottom. As carbon dioxide bubbles accumulate on the outside of the mothballs they eventually become buoyant and slowly rise to the top. While at the top the bubbles break and the mothballs sink again.
This will repeat until the liquid runs out of carbon dioxide.
As the mothballs are not soluble in water, if you use a clear soda drink you can still drink it when you are done (after removing the mothballs so you won't risk swallowing one and choking), but it of course will be somewhat "flat".
What can happen if baking soda and vinegar mix?
When vinegar is added to baking soda, a chemical reaction occurs that produces carbon dioxide gas. This reaction is exothermic, meaning it releases heat, causing a slight increase in temperature.
Everybody knows that baking soda and vinegar make a reaction similar to a volcano
it is cemical reaction
It will still fizz, but fizz less the more water is added to the vinegar (acid) solution. Vinegar is already a diluted solution of acetic acid, and is mostly water.
baking soda reacts with vinegar to produce sodium acetate and carbon dioxide
it bubbles
The baking soda dissolves in the water

You will get a frothy red mess. The baking soda and vinegar will combine to produce carbon dioxide as the acid in the vinegar combines with the base in the baking soda. The red cabbage will will make it colorful, and the water will slow the reaction. On the other hand, red cabbage and vinegar will make a nice pickled cabbage.
99 % of the shell is dissolved.
When vinegar is added to water, the vinegar dissolves in the water, since vinegar is primarily acetic acid dissolved in water. This solution may lower the pH of the water, making it more acidic.
