Don't look up

This is a pretty simple prank: It involves my classmate, Professor Marius Jansen ’44, a very respected member of the Princeton faculty for many years.

We both roomed in Dod Hall freshman year, and Marius’ room was directly over the main entry.   Marius taught me how to fold a sheet of paper back and forth many times, creasing it, folding it, and tucking in the edges to form a hollow cube, which could be filled with water.

He had the brilliant idea, then, of dropping these water bombs in front of people entering the building. Of course, we were both extremely careful not to hit anyone unless it was a good friend.
