The Physics of Hurling Water Balloons

Mr. Knapp recently proposed an interesting challenge to his physics class:

Take your combined knowledge of the physical laws of nature. Add €20. Build a machine that will launch water balloons with a single target in mind… your physics teacher.

Challenge accepted!

And the result? This brilliant piece of engineering made simply of four bungee cords, a funnel, a couple of washers, and a shoelace.

The entire school came out to watch as our young physicists experimented with their machine.

Then, the moment of truth…

After five attempts, Mr. Knapp was left as dry as the Arizona desert. Until of course, reinforcements showed up.
