Blow

Ok, so this is technically a kids craft, I think, but it is so much fun!  As long as you don't pass out.  Saturate a brush with any kind of water based paint, making sure you get it very wet. Then take a straw, and blow across it.  This part may take a few trys to get it right.  

 

It's actually quite meditative once you get going.

 

Keep going till you get just like Pollock.
