Robot Jars

I extruded a bunch of cylinders for kids to transform into robot heads by adding coils rolled on texture mats. I have a Bailey four inch extruder in my classroom and it is wonderful for making hollow tubes and for making coils quickly. The key to making these with kids is to let the hollow cylinders set up so that when the kids add the robot parts, the cylinder doesn't squish. The cylinders need to be leather hard when the kids add the facial features and parts to them.
