Flour Power

I had an idea the other day. . .  I thought about all of the times that I have thrown paint at some people, but I have never thrown something that wasn't a liquid.  So, I went out and bought 25 pounds of flour and a dress from salvation army.  Surprisingly, this whole thing cost $10.  It took four of us to accomplish, but it was worth it.  Do you have any other ideas of what I can throw at more models???
