What in the vinegar or baking soda makes the bubble not pop?

im doing this research project on the zoom website. you can look for it and try to help me.

u think i have to search thigns about physics, but i still need help to find more details.What in the vinegar or baking soda makes the bubble not pop?
Vinegar is acetic acid: CH3COOH

Baking soda is sodium bicarbonate: NaHCO3

Mixing the two is simply and acid base reaction.

CH3COOH + NaHCO3 ---%26gt; CH3COONa + H2CO3

That last product is carbonic acid which quickly decomposes into

carbon dioxide and water:

H2CO3 ---%26gt; H2O + CO2

The CO2 is what you see foaming and bubbling in this reaction.
