• A Dash of Pepper
• Liquid Dish Soap

Steps
 
1.  Fill the bowl with water.

2.  Sprinkle a dash of pepper in the bowl of water.

3.  Add a drop of liquid dish soap.

The pepper scurries away from the soap.

This is because the soap breaks the surface tension of the water and the tension on the rest of the water pulls the floating pepper away from the soap.
