Hands not believe

Prepare three bowls of water: one - with a cold, the other - with the room, the third - hot. Ask your child to omit one hand in a bowl of cold water, the second - with hot water. After a few minutes let it plunge both hands into the water at room temperature. Ask hot or cold it seems to him. Why is there a difference in sensation of hands? Is it always possible to trust your hands?
