Trick your Fingers

 Sham S. Misri
 

This trick has a scientific twist.

Fill one bowl with cold water and put some ice cubes in it. Fill second bowl with hot water, (the water should be hot to touch but not very hot to be uncomfortable).  Fill a third bowl with tap water at room temperature.

Put one of your child’s hands in the bowl of ice cold water. Put his hand in the bowl of hot water. After a minute, put both of his hands in a bowl which has water at room temperature.

Although both hands are in the same bowl, the water will feel cold to the fingers that were in hot water; and hot to the fingers that was in cold water.

The child feels excited.
