i tried with sprite, 7 up, water, and alka seltzer, my furst trial were I counted how many times the raisins hit the surface the total was 0. we thimed it 4 onlyy 1 min. I tried to tell my science partner that we needed longer. the second trial the 7 up went up and down realy fast at first then just stopped after 4 times. Is the normal? I did this for my 7th grade science project.

2 of the rasins were at the bottom of the glass and 1 went up and down.

Our hypothesis was right, because the bubbles sticked to the raisons. And they floated too. We learned that expiriments are actully fun.

One raisin floated to the top and two sinked to the bottm of the cup. And then they all sunk. They only moved a little bit.

Our hypothesis is right but only one didn' t flaot, and the raisin when up and down.

When we combined the 3 raisins with the soda the raisins attracted bubbles but one floated to the surface.

It was incredible. I loved doing it freaked my 5 year old sister out!

David, age 13 of Grand Rapids, MI wrote:
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.

When I did this experiment it was funny at first, when I first droped the crasin it sunk right to the bottom! It was so cool. you shuld try it to!

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 were bouncing up and down within a secound after I put them in. I'm doing this for my 7th grade sci project! But if anyone could answer me: how do I present the data.

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.

They started dancing and I could see how bouyancy works with raisins. I hope I do good on my science presentation!

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!!!

when I did it, it went up and down like a ball. I thought it was magic. it is cool.

it was so cool! at first my mom thought the soda was eating the raisin up but once she realized what was happening she thought it was cool too.

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.
