Today's experiment is another classic.
I recall observing this one in elementary school myself! :)
It was still fun to watch these many years later.
Dancing Raisins Experiment
What? Dancing raisins?
Yes! Didn't you know that raisins like to boogie?
No, well then turn up the music and get ready to witness
some fun as you watch raisins dance in this simple & fun experiment.
What You Need:
sprite/7-up or other clear soda
clear cup, bottle or other container
What To Do:
1. Add your clear soda to your container/bottle/cup
I filled our bottle about 1/3 of the way.
2. Drop in some raisins.
How many? That is up you.
3. Make sure you have some music playing
& watch closely as those raisins get down! :)
For comparison we also did the experiment using plain water.
Ah, no fun dancing raisins this time. :(
The science behind it - Raisins sink in water because they are more dense. Soda on the other hand has carbon dioxide and forms bubbles of gas. Those bubbles attach themselves to the raisins and make it float. When the bubbles pop, the dense raisins fall back to the bottom of the jar. This up and down motion caused by the bubbles makes the raisins appear to be dancing. FUN!
Who knew raisins were the life of the party?
