here's what you do, find out what kind of aircondtioning the school has, if it is an old school school, they will probably have a swamp cooler kind of unit that runs the whole school. find out where the coolant goes. now as you are learning the system, piss in soda bottles and store in a safe place(not your locker) preferably hidden near a school dumpster. then one night b4 a hot sunny day, pour that in the coolant storage and dont come to school the next day. on the last day or second to last day would be best. they did an illegal search on you, they violated your privacy and your dignity. this will get that back ten fold.
