Compressed Air

So the trick here is that I'm trying to engage some interaction here. Can anyone guess what this is a photo of? I will tell you what is in the background, its a tv. It made for a really good black backdrop in order to take this picture. Take you're shot at a guess, and check back here Monday for the answer. I'll change the post to title to reflect what it really is as well as give a short description of how it came about. Enjoy!

UPDATE:

Thanks to those who took a stab at guessing, and for the rest that looked and wondered, here's an explanation. Those cans of compressed air, when held upside down and used will spray out the liquid inside. Now for the record, I have been reading out of curiosity to find out whats inside those cans and it isn't air. But by using that terms I'm sure everyone will know what I'm talking about.

Anyway, the how. Jenn held the can upside down and in front of the tv, like I said before. Somehow in some freak chance of luck, in the first attempt to take a picture this is what I got. I thought it was pretty neat looking and wanted to share. And now you know!
