Of course, there were inherent lessons about colour theory.

Naturally, there was experiments in viscosity.

Sure, there were discusions about smells and diffusion.

But really, it was just awesome to get naked and paint in the shower with food colouring and shaving foam* and then pretend he was a monster.  

Even better? He pretended to be a fireman and hosed the whole shower down afterwards.

Awesome**.

** I've begun using the word "awesome" with increasing frequency. Its possibly a sign of my mental decay. Or a deep connection to my Americanness. Or maybe because its just a good word. Awesome.  Though, if I start using "dude" too much, please send help.
