I remember during spring break this year a couple friends of mine went around town pulling a bunch of pranks they had planned out. One of the pranks was to go into a really tall building with an elevator, get in the elevator, and while inside, get dressed in hazmat suits and put yellow "QUARANTINE" tape over the elevator entryway. They pushed the buttons for every floor on the panel. Whenever the doors opened, they took out fake geiger counter props and started waving them all over the elevator. Not a single person got on the elevator whenever the doors opened. When the elevator started moving from the second-to-top floor to the top floor, they took off the hazmat suits and removed the tape, and exited the elevator when the doors opened. They then waited like 5 minutes before going back down again and then leaving the building. It lasted about 20 minutes or so.
