Too brittle. Just an exercise in weird frustration, really. Now I have to take responsibility and try to figure out how to repurpose this ridiculous pile of plastic in front of me. Good idea though. When you open a can of styrofoam putty, all you have to do is do your homework in time to throw away as little material as possible. Worst case scenario, you'll lose three dollars of foam in a glass, and I'm sure the foam gods will accept that as an offering. Try not to think about it too much.
