Dunk Tank

Okay, I was bored, so I decided to make a dunk tank. There. Done. Boom. xD
So what happens is, two redstone torches keep the pistons you stand on out, and so if you hit the painting with a snowball, it pops off, hits a pressure plate, activates some redstone, which activates two dispensers, which fall on pressure plates, which makes pistons pop the restone torches off. xD So, obviously, this is very over-complicated, but I stink at redstone, so this is big for me. There is also a room the person falls into after they get dunked, which lets them go back to the surface. :D Re-setting it up is a pain, but it's well worth it. :)

Comments or creative critisism would be very appreciated. :D
