Here’s a really easy experiment you can try at home with your little ones.
- clear carbonated soda
- clear tall glass, bud vase, etc
Step 1. Pour clear the clear soda in the tall glass container.
Step 2. Add 4-6 raisins
What happened to the raisins?
They sink because they are more dense than the soda.
Step 3. Wait and observe
What happens next?
The bubbles of carbon dioxide from the carbonated soda attach to the wrinkles of the raisin and give the raisin lift and the raisin rises to the top. When it reaches the top, and the bubbles burst, the raisin falls back down.
