Before you get upset, waivers were signed before the spraying.
In case you've never encountered Pepper Spray, this stuff is no joke! I carry one, and one time in college, I was curious, so I sprayed it quickly on the ground in my dorm room and POOF! In a matter of seconds, I was feeling the burning effects without even being in direct contact. Airing the room out wasn't a simple task either. It lingered, as the windows in our dorm did not open. Dumbassery at it's finest, but I sure did learn from it.
