Yahoo Sports: A footballer goes down with an injury -- whether real or imagined -- and the team doctors come jogging out with a bag of tricks in an effort to coax the writhing player back to their feet. Almost inevitably, no matter what part of the body the player is clutching in anguish, the attending doctor pulls out an anonymous looking spray can and gives the player a liberal dousing of white mist.
LOL, i was always curious about that. :P
Knew about the ones for numbing, didn't know about the cold water for overheating
yeah, that was interesting. Pretty sure it wasn't meant to be used like that, but leave it to the professional i guess
