小苏打和醋为什么会冒泡

When I mix baking soda and vinegar in my kitchen, tiny bubbles appear right away.
The fizzing sound tells me a quick change is happening inside the cup.
I can feel the cup get cooler as the mixture fizzes and bubbles rise.
My mom says this reaction helps clean sticky spots on our sink.
We use it to unclog the drain when water flows too slowly down the pipe.
It’s safe to try at home if an adult watches me carefully.
The bubbles stop when all the baking soda has reacted with the vinegar.
I always wear goggles because splashes might sting my eyes a little.
This simple mix teaches me how everyday things can work together in fun ways.
After cleaning, I rinse everything well so no sour smell stays behind.
