MATERIALS NEEDED FOR DANCING GRAPES SCIENCE EXPERIMENT:

• Seltzer Water
• Grapes
• A large vase

HOW TO MAKE THE GRAPES DANCE:

1. Start by filling the base about 3/4 full of seltzer (fizzy) water.

2. Toss in a handful of grapes (raisins would work too).

3. It takes a few seconds for the grapes to start dancing but once they do they keep going for quite a while! So cool!

WHY DO THE GRAPES DANCE?

The grapes are slightly heavier than the water so they naturally sink to the bottom, but the carbon dioxide bubbles attach to the grapes causing them to rise to the top. Once the grapes reach the top, the bubbles pop and the grapes sink back to the bottom where more bubbles attach to them and the process repeats.
