Heh. Not that it matters, what with your pretty pink water. What's that thing at the top?
Avalanch is correct, it's the radiator.
Pinks a manly color, didnt you know that?
The water is pink because I originally had red in there, but after replacing the water and traces of the coloring being in the radiator (since I didn't bother to remove it and flush it completely) the result is technically a really light red, buuuuuut as we can see with the the way the particular coloring is and, being very faint, and the cameras flash it comes out rather pink looking.
The color I used wasn't very 'red' to begin with. Food coloring red woulda been better, but I wasn't ever sure if food coloring was ok to put in there...some people said it was fine, others said it wouldn't, so I got a liquid meant for water setups......buuuuut yeah overall I was disappointed with it.
