Me and a couple of friends did something like this. We printed loads of pictures of cats and stuck them to the ceilings all around school. People were trying to find every single one we'd hidden. Good times.sasquatch99 said:Get the No More Nails glue and glue as much stuff as you can to the ceiling.
Or come into school all on Harley D's while either Born to be Wild by Steppenwolf (I think) or Wheels of Steel by Saxon playing incredibly loud. Preferably you balancing on the bikes while playing the songs with your friends.
