One positive (an probably the ONLY positive) thing is that the students clean up this mess afterwards.
It's harmless fun, but a real waste. I can only hope that they recycle the paper, so that it doesn't end up in a landfill someplace.
This has got to be the stupidest thing I have heard of in a while. a waste of trees and Just can't wait to see what a tree hugger would say about it. wait till it rains it is going to be a mess. I would smack my kid if he or she thought this was a good idea
