Obviously, it jumped up and down. The explanation is because the acid in the vinegar and baking soda combines made the dissolved carbon dioxide in those little bubbles, which rises to the surface. it attracts themselves to the raisins, which doesn't add much mass, but makes it rise. Once at surface it pops.

We noticed that the bubbles went up before the raisin. Our raisins bounced very slowly. We tried to make our raisin jump faster by throwing it in hard and tapping the cup.

The raisins popped up and down. We added Alka-Seltzer and made extra bubbles. We also blew with a straw and the raisins popped up.

The raisins began to dance. We also tried the experiment with vinegar, water, and added baking soda. When we added the baking soda, it exploded. It was awesome!!! Then the raisins started to go up and down, up and down. You should really try this!!!

We put 3 raisins in and then they started going up and down for about a minute until all the carbon dioxide formed ions, then the raisins stayed on the bottom.
