DANCING PAPER CLIP

Impress your kids with a "Dancing Paper Clip".
Fill a baby food jar with water and drop a steel paper clip into it. Tell your child that you can make the paper clip dance up and down in the water without touching it. Then move a magnet up and down outside the jar to make the clip dance. Let your child try it. Explain that the magnetic force form the magnet passes through the glass and water to make the clip move.
