Thanks for all the clay ideas! I'll let you know how it goes!
I usually make the kids solve a problem with clay as the medium. They
actually have to THINK and be ORIGINAL!
One problem I gave was: Create a clay container that is fastened in some
way. I did not specify, fastened with clay or not. I got quite a few
original ideas....one was fastened with a large saftey pin, another had
straps that kinda looked like buckles made of clay. The latest problem,
using the pinch method, was entitled: It's all in the edge.
