Here is a cool science experiment to do with the kids.
What you will need
A 2 litter bottle of Diet Coke (Apparently diet Coke with caffeine works the best, but any carbonated soda can get a similar reaction.)
- Mentos Candies (About 1/2 a package per bottle.)
- You just drop the mentos into the bottle As quickly as you can and watch it erupt. The first link says that you can turn it into a rocket if you quickly replace the cap and turn the bottle upside down. But when we did it, we only got 3 mentos in the bottle before it erupted all over me. So I don't see how it could work unless supper man tried it with his supper speed :) It was cool and we will certainly do it again.
An explanation and history of the experiment can be found here from wikipedia.
I basically told the girls that carbon Dioxide is what makes the pop fizzy and bubbly. When you drop the candy into it, there are lots of VERY little holes in the candy and the holes react to the carbon dioxide to make TONS of bubbles out of the pop. Since bubbles are bigger than the pop there is no more room left in bottle, so the bubbles/foam shoot up into the air.I first got the idea here from mintagehome.blogspot.com
I got the picture from google images, there is no way I could get a picture of this on my own.
