- 4 cups of water
 - an apple
 - 2 teaspoons of salt
 - a bowl that can hold 4 cups of water, and the apple
 - a potato peeler
 - a knife
 
- peel the apple
 - carve a funky face into the apple
 - pour 4 cups of water into the bowl
 - put 2 teaspoons of salt into the water
 - place the apple into the bowl
 - put something on top of the apple to keep it from floating up, like a saucer
 - leave the apple in the water for 24 hours
 - after 24 hours, take the apple out of the water and use it to scare people!
 
P.P.S.: you will probably want to throw the apple away after a while...it will start to STINK!
