Ice cube drawing

Ephemeral Ice Drawing
Here's a very cool project for a hot day. Supply your child with several sheets of colored paper and an ice cube to draw with. As the ice cube melts, it will create a trail of dark marks that fade as they dry and then -- poof! -- disappear completely. For an easy-to-hold twist, you can make the ice in a plastic ice pop mold with a handle. This can even be done on the sidewalk.
