Dancing Raisins

Today we did a experiment where we made raisins dance!

It was a lot of fun.

We put lemonade in a glass and then added some raisins.
We enjoyed watching the raisins bob up and down in the glass.

We discovered this happened because the carbon dioxide in the drink made bubbles on the raisins.  Then the raisins floated to the top.  When the bubbles popped the raisins sank again.
