Toothpick Star

The concept behind this is too advanced for A, but it is a neat visual. 

Take wooden toothpicks & break in half,  but not apart.  Place then so their center (folded) parts touch.  Drip a little water at a time on the center & watch the toothpicks move apart.

(This works because the the water travels through the toothpicks using capillary action)
