what are some really good and awsome science fair projects?

Question

At scholl were having a huge science fiar and i really want to win it. I would really like it if there was a chemical reaction or something that would make people say wowww.

Answer 1

You can try doing one of those projects with an exploding volcano. It's a really simple chemical reaction that causes "lava" to flow out of the volcano. There are several sites on the web that can instruct you how to build one of these. The major ingredients are vinegar and when you add the baking soda, the reaction (explosion) occurs.
