These little guys can groove!
- tall clear glass
- raisins
- club soda that has a lot of bubbles (This won't work if the club soda is flat.)
- First, pour the club soda in the glass.
- Next, drop in half of a raisin.
- Wait at least 20 to 30 seconds and watch what happens to the raisin. (The raisin should rise and fall.)
- The reason why the raisin floats to the top is because the bubbles stick to the sides of the raisin and make the raisin more buoyant. Buoyant means that something floats more easily. The bubbles make the raisin float the way a life jacket makes a person float.
Now, start to experiment. Think of a question that you'd like to answer. Like, "Can I get something that is heavier than a popcorn kernel to float using bubbles? Will a walnut or a super ball float?" Make a prediction, test it out, and share your results in the ZOOMsci feedback area.

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!!!

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.

Well I poured the club soda first then droped a few raisins then after 20 or 30 seconds I begun to see that they started to go up and down It was amazin I thought it wasnt going to work but it did!!!

We give this experiment a big thumbs up! We had to be patient, but after the raisins sat in the cup for awhile they really began to dance. Many of us noticed all the little bubbles that formed around each raisin. Then we tried this experiment with almonds and many of us think that the almonds were even better dancers!

When we dropped the raisins into the club soda, they fizzled, they danced a little, and floated to the bottom. We did the experiement 3 times. It was awesome! THe first time we did it it took 9 seconds for a raisin to dance. The second time it took 44 seconds and the third time it took 10 seconds. One student thought the first time happenend the fastest because there was more carboniation the first time we opened the bottle.
