    This is not original, but I thought it was pretty clever...

    You go into a house and there are three light switches on the first floor operating three lights on the second floor. You must figure out which switch corresponds to which light, but you can only go upstairs once. How do you do it?

    ok. you flip two switches, wait a few minutes, and turn one off. Go upstairs. If the lightbulb is on, it is the switch you left on. If it is warm, it is the switch you turned off. If it is cold, it is the switch you did not flip.

    Ah, you didn't know they were flourescent lights? No heat.
    However, if you were fast enough, you could rush upstairs and see
    what light beams are closest to the lights....

    a light beam obviously moves at the speed of light so how would you move up stairs fast enough to see the ?

    You go up to the room and set up a sequence of mirrors down to where you stand.

    Or tie strings to the switches.

    Well I said, IF you were fast enough. Remember, the light is
    coming towards you so maybe you could distinguish which beam
    is in front.

    You could set up CCTV upstairs then go back down and watch what happens.

    I heard a puzzle the other day. No trickery - just mental maths. No paper or pencil allowed.

    If a man and a half dig a hole and a half in a day and a half how many holes does one man dig in a week

    since you can have half holes in this one i'd say the answer is 14/3 holes. oh and since it's a third of a hole and not half a hole, maybe its alright for the other thread too

    you can't have half a person nor "half" of a hole because that "half" is still considered a hole...

    That would be 4 and two thirds holes.
    (Two thirds of a hole!!!!!! Half a man!!!!!!?)
