Here's one to bamboozle you... There's a room with no windows and only one door. Inside the room there's 3 lights. Outside the room (away from the door there's 3 separate switches, each operates ONE of the lights. You can only enter the room ONCE, how do you tell which switch operates which light???

Flip the first switch, wait 60 secs, flip it off. Flip on the second switch and enter the room

If the light bulb is warm but off then it is switch 1, if it is on then it is swicth 2 and if it is off and cold then it is switch 3

I think rekstout is correct but just to clarify things: Whichever bulb is warm is operated by switch 1; the bulb that is on by switch 2 and the other bulb by switch 3.
