Scared Pepper


shallow baking pan
pepper shaker
bar of soap


1) Pour in enough water to have it about an inch deep. Let pan sit until the water is calm.
2) Sprinkle pepper enough to cove the entire water surface.
3) Touch one corner of the bar of soap to the center of the water, and watch what happens.

Explanation: The pepper can float because of the water's surface tension. Soap breaks the surface tension. When you touch the soap to the water, some dissolves into the water. When the surface tension breaks, the pepper is pulled to the edges of the pan.
