Water Cooler Cannon

I can see one of my students inventing this. I am almost
surprised none of them hasn't thus far. Tuesday night at our
Science World's Fair I can't wait to see what they have imagined!

This new cannon uses water coolers. To blow down walls. Hum..

I have requests to do the Egg Drop Contest next or I might
have to try something like this. It has me thinking...
