We followed the scientific method along the way and made vokis and videos of our work.
= Our favorite experiment: = = Make a geyser = You will need on two-liter bottle of soda and a half package of Mentos candies. We tried mint and fruit. The mint worked better. A geyser tube (available on the internet or at science stores) makes the experiment easier, but it is not necessary. Drop half a pack of Mentos into a bottle of soda. Stand back and watch your geyser erupt 20 feet or so into the air!

You will need one cup cornstach and one half cup water. =Floating Egg= You will need one raw egg, one half full glass of water. about six tablespoons of salt (we needed more). Carefully drop the egg into the plain water first. Take the egg out, add the salt, place the egg back into the water and watch what happens. media type="custom" key="15862664"
 * When showing other people how it works, stir slowly and drip the quick sand to show it is a liquid.
 * Stirring it quickly will make it hard and allow you to punch or poke it quickly (this works better if you do it fast rather than hard).
