A simple puzzle?!
Question: There are two rooms. In one is a lightbulb in the socket of a ceiling light fixture and in the second room there are three light switches on the wall. Between the two rooms is a door which is closed. How do you determine which light switch turns the light on? You can turn each light switch on and off only once and you can open the door only once.

turn first switch on, wait half an hour, turn it off
turn second switch on, open door
if the light is on, it's the second switch
if the light is off, go over and touch the lightbulb...if it's hot it's the first switch and if it's not it's the third switch
=]
just open all the wiring system and then look for which wire for which one
then open the door
then open the swith on
Open the door and LEAVE IT OPEN
that way you can see into the next room
then switch each switch on in turn and see which makes the lightbulb light!
OR
Turn the 1st one on and leave for a while
Turn it off and then turn the second one on quickly
If it is on, it's the second switch, if it's hot but off it's the first and if it's off and cold, it's the third!
But the first one is better!
Hav a star!
Hey, others are copying me!
switch on all the three the first time itself
just, you know, leave the door open
