TOOLS (1)

TARGET
Anyone inside a room with the door closed
HOW-TO
Pennying a door is done from the outside to lock someone in their own room. It is done by jamming pennies into the hinge side of the door (away from tbe knob and where it normally opens). The theory is that the pennies prevent the door from pivoting through the small space as it tries to open, thus preventing the motion from working.
While it can work on the right door, it doesn't work very well. Your best chance is making sure the pennies are pushed in as far as possible to get to the pivot point, otherwise the door will pivot and just push the pennies back out.
