Science Play~Dancing Popcorn

I'm always looking for simple, fast and fun science experiments we can work on.

Here's one we have done recently and had tons of fun with.

For dancing popcorn, you need:
un popped popcorn kernels,
baking soda,
water,
White vinegar
A clear container such as a drinking glass or an old bar from the recycling bin.

What we did:

We added water to the clear container, added some baking soda and stirred it until the baking soda was disolved.

We then placed about 20 popcorn kernels into 2 glasses. Then we added some vinegar.
 At first nothing happened, so we talked about waiting to see, or adding more vinegar. We decided to add more vinegar to one and more baking soda to the other and waited.

Within a couple of minutes the kernels were moving from the top of the glass to the bottom, going up and down.

The popcorn "danced" for several hours, and although we left the project after awhile, we went back to see how much they were still moving every few minutes.

Have you ever tried this, or an experiment similar to this? I've read about doing this same idea using bits of uncooked spaghetti noodles.

Peace, joy and love until next time!
