I am looking for a large sphere/ball for a science experiment. The sphere needs to be hard and durable enough to support one or two hundred lbs without permanently denting or deforming. It needs to have a diameter of between 12 to 24 inches. I would prefer plastic instead of metal, but I can use metal if needed.
Optimally, I would like to find a 2 inch think, 20 inch diameter, hollow sphere made of a hard plastic. Suggestions are very welcome.
Thanks!
