    Light switch question

    There is room with a light bulb in it, there are no windows in the room. There is one door, the door has no window in it.
    Outside the room there are three light switch's, you cant see any wires or take them apart.
    Only one switch turns the light bulb on, how can you tell which one it is everytime.
    Oh and you can only open the door once and it closes automatically. The switch's are round a corner so you cant hold the door open and turn the switch's.

    This isn't to hard(can't be i figured it out).
    All spelling mistakes, syntatical errors and stupid comments are intentional.

    Turn one #1 for 2-5 min.
    Turn it off
    Turn on #2 and run to the other room.

    the lightbulb on is #2.
    the lightbulb hot is #1.
    nothing is #3.
