Quicksand



By Danny


MATERIALS NEEDED
1 large bowl
1 spoon
1 sheet of newspaper
1 1/4 cup cornstarch
1 cup of water

PROCEDURE
1. Put the cornstarch and water in the bowl.
2. Mix with the spoon until they are thoroughly mixed and look like paste.

RESULT
You have created a substance that seems hard. When you hit it hard with you fist the surface seems to stop your hand from going through the mixture. But when you push your fingers in slowly, they slide into the bottom of the bowl.

WHY?
The molecules of the goop are larger and hook together unlike the molecules of water.
