this senior class prank of the class ahead of me

the video is self explanatory http://www.youtube.com/watch?v=U9hLjrvvbZ8

then my class put a car in that same hallway, put up paperwalls in between each hallway wall near the fron and rear of the car, then filled that space of with crumpled paper concealing the fact that a car was in there until the paper was removed
