Splice into the PA wires, and play some random shit over the PA system.
or
Build an army of homework eating robots, and take over the school. With your might robot minions at your feet, no one will deny you. Ask them for money or something.
Now on the other hand, I have a non electronic prank to do.
Collect three pigs from your agricultural area (If you have one) and write the numbers 1,2, and 4 on the sides.
Then grease them up and let them loose in the school.
Theyll spend forever looking for number 3.
