Here is great story about the power of flour that goes back for a long time

in the world and can afford anything:-)  I just shows you how cheap flour really is if dead broke countries can waste it like that.  Of course they aren't nearly as dead broke as America is by quite a large margin but they can't print Euros to pay off their debt.  We can print as many dollars as we want.  I too hate wasting anything.  I say make them throw something environmentally sound, like dust at each other and use the flour to make pitas for the poor.  Or better yet, just make pitas for the poor and skip the throwing of anything.  Bet they won't change no matter what though.
