Invisibility..

Alright...who is going to try out Schlieren photography (which you can actually do yourself at home!), and report back to me??? Just cool would it be, to photograph the invisible like this??? :D Apparently, it is completely able to be done by the average shmoe with a decent camera and a $50 piece of equipment off eBay. Come on! You know you want to know what your sneeze looks like! You know you do! :p
