or eat all their carrots

Did you know that you can rupture waste lines by flushing multiple toilets(3 or 4) at the same time.
knowledge is power.

That takes multiple people. If you want to fuck up the plumbing, use stuff that is freely available. There is a reason for the "do not flush" warning on packs of tampons, maxi pads and condoms.

That is a Myth mate. Sorry to tell ya. I know about 5 people who flushed the toilets all consecutively and nothing happened.

yea def. myth i always used to fuck with the toilets

Sorry to change the subject, but does anyone have some ideas as to messing with teacher's heads? I'm fully capable of reading a psychology text, but I'm wondering if there are any tried methods I should know of.

umm since you asked nice..

I mess with my teachers by (well if I don't like them) by getting into a fight with them to the point where they are gonna send me to the office then they always back out since im willing to.. then for the resat of the time i have them i sit and make noises and cooments and do shit to the room

once, it was a teacher we hated
everyone in the grade showed up two hours early with 100 crickets
since the teacher kept the room locked we let them under the door
100 kids * 100 crickets = 10,000 crickets
a kid would stand at each end of the hall with a stack of books to drop if someone was coming
school started and you couldn't hear anything over the crickets not to mention they were everywhere
they couldn't have the school fumigated because we would have had to miss like a week of school
6 weeks later there would still be that one cricket going chirp chirp
we would all bust out laughing and it totally pissed off the teacher

then another time after the crickets, but to the same teacher we took and soaked pantyhose in 8 hour epoxy and then wrapped them around each tire of his car after he got to school and hour early
so drying time was 10 hours because of 1 hour tutorials
it was rock hard at the end of school
his car wouldn't even budge when a winch was used (tore off his front bumper )
he had to get someone with a cutting torch to cut the wheels off the car
it was there for a week

In middle school me and my friend rounded up a bunch of the Axe/Tag etc cans from the kids who were in phy ed. at the time. Later we took the backpack full and smashed them against lockers so they would be constantly leaking and rolled them down the hallway before kids got let out of school. It was fucking foggy.
High School, we snuck into the kitchen and found hundreds of frozen beef patties. Frisbees. Self explanatory. We also bought tampons and dipped them in V8 juice and threw them at hallway windows. Good times.
I still don't have any clever ideas of a senior prank :/.
Oh almost forgot. If your school has indoor stairwells that you can see all the way down, fill a Nalgene water bottle to the brim with a liquid and drop it. Sounds like a fucking bomb going off.

steal your teachers phone and take pictures of naked 5 yearolds
