Using a two liter bottle of Coke or Diet Coke and a roll of Mentos candy, make a small paper funnel at the top of the plastic jug and stand back. The candy will immediately react with the soda to create an eruption that causes soda to fly up to ten feet in the air. The reaction comes from the pores on the candy coating, combining with the carbon dioxide in the soda, which creates an enormous amount foam, that is forced out of the bottle at tremendous force.
Mix four ounces of school glue for every half cup of water, depending on how much slime you want to make. Add several drops of food coloring; as well as a tablespoon of borax powder, stir the batch until it is no longer lumpy and you've got slime. It can be molded and sculpted temporarily, but should always retain it's goop-like consistency.
Mix a 1/4 cup of sugar, a 1/2 cup of milk, a 1/2 cup of whip cream, and a 1/4 teaspoon of vanilla in a resealable plastic bag. In a separate bag, add two cups of crushed ice and a half a cup of salt on top of it. Once you have added the salt, place the smaller bag containing the sugar, milk, whip cream, and vanilla inside the bag. The ice will react with the salt to make the ingredients solidify, and make the ice cream harden. After eight to ten minutes of moving the ice cream bag around inside the ice bag, the ice cream should be solid enough to eat.
You can make your own solid rock candy by dissolving four cups of sugar into two cups of boiling water on the stove. Stir the sugar water until it is completely dissolved and pour it into an empty jar. Place a weighted string or long wooden stick into the solution and cover it with wax paper for five to seven days, making sure to keep it completely undisturbed. Boiling the water and sugar creates an unstable, supersaturated solution, which only becomes stable as the mixture cools and solidifies.
