How to Have an Ice Cube Melting Contest

Make several trays of ice cubes; make sure they're all the same size.

Assemble players outside.

Give each player an ice cube.

Tell the players that the object of the game is to melt an ice cube as quickly as possible.

Tell them they can use any method they want - placing it in the sun, putting it in water or holding it in their hands. The only thing they can't do is put the ice cube in their mouths.

Watch to see whose ice cube completely melts first. This person is the winner.
