Kids Science Experiment: Bouncing Raisins

This is another baking soda and vinegar science experiment that kids can easily do at home. When a base substance like baking soda has a chemical reaction with an acid like viengar, they create a new substance. In this case, it creates the gas carbon dioxide. The chemical reaction creates bubbles in the liquid which stick to the rough surface of the raisins and float them up to the surface. When the bubbles pop, then drop to the bottom of the glass making it seem like the raisins are bouncing in water.

Here’s what you’ll need:

How to do it:

  1. Half fill the jar or bottle with warm water.
  2. Add 2 teaspoons of baking soda.
  3. Add in your raisins.
  4. Top up the rest of the jar with vinegar.
  5. Wait a few seconds for the reaction and watch your raisins dance.
The carbon dioxide bubbles are lifing the raisins up. They drop back down when they pop.
