Explode a Messy Volcano!

Make a messy volcano that explodes all over. Here's how.

1. An empty juice or water or soda bottle - this is going to be your volcano. (If you want to decorate it before you start the experiment, go right ahead! If you surround the bottle with playdough or clay, it will look very much like a volcano.)
2. Some baking soda
3. Some white vinegar

Move your volcano to a safe area. Preferably outside. First pour about half a cup of baking soda into the bottle. Then, keeping your head away from the top of the bottle, start pouring the vinegar into the bottle until your volcano explodes!

This is a great idea for your science project or just for fun. (Please do this with adult supervision. It sure does make a mess.)
