If you ever wondered what would happen if someone who was into practical jokes took steroids while dreaming up their devious plans, you might want to check out this website. The Foil Project is a dorm room covered in tin foil.
Warning! The video of the reactions have explicatives. You might imagine what was said by those who actually owned the room.
Disclaimer: I don't know that steriods were or were not involved.
