polycarb :)

Polycarb does shatter if you hit it hard enough. With the forces unleashed by the spinners in a antweight arena I wouldn't be surprised if it was polycarb. They way to tell the difference it to look along the side of the sheet. Acrylic looks white where as polycarb looks a dark grey to black. It doesn't matter how it was cut it will be this colour regardless.
