I remember playing with something similar to this in my kindergarten classroom. The teacher would change the sand to water or rice once in awhile for a change. I loved the feel of rice running through my fingers. Click on the graphic for the instructions. It’s from the July/August 2005 issue of Family Fun magazine.

Darrell and I plan on making one this weekend. We already own the black tub. We bought one for Bren at the beginning of summer. I like the idea of adding the table part. It’s easier to play in that way.
