And if you get an overly large Mac, will it be a BigMac?
Bad puns aside, I love plastic. Especially plastic that is easy to work with. I just found out about ShapeLock plastic, which I'll hopefully getting soon to help with halloween costumes. It looks and sounds much easier to work with than polystyrene (which enters its glass transition state at 95 C, compared to ShapeLock's ~ 72 C). Though wet and shape cloth might be a good alternative if this turns out to be crap; bad thing there is it is hardish to come by it seems.
