beans and rice in a seive

I found a good use for our broken salad spinner. It is now serving as a sieve to sift rice and beans.

It was a challenge for the children to shake the spinner over the bowl to keep the rice from spilling all over. But they learned that shaking the spinner caused the smaller grains of rice to fall through the openings...

leaving the larger beans behind:

A way to easily sort/grade different sized particles!
