There is a room(4walls, a roof, no windows, everything is solid, and you can't see in).There is only one door.You are outside the room.Near the door, there are 3 switches.One of them turns on a lamp that is inside the room.the others do nothing.You can open the door only once.Can you find which switch is the correct switch>? 
well if you can open the door once then geez... open it, block it with something so as it would not close by itself(although highly unprobable) and then check all the switches...when you see the light you know you have found the switch 
Well, the riddle has a perfectly logical explanation, and doesn't need this kind of tricks.And no, unfortunately, this is not the answer.The door can't open more than once, and it can't stay open in no way!You also can't open any holes or anything like that...When you open the door, you can get into the room, but nothing more...
My answer has a 50-50 chance.
You turn on two switches and go in the door. If the lamp is not lit, then you know which one it is.
But if the lamp is lit, then I have no idea what to do.
Open the door and start hitting the switches. When the lamp turns on, just go inside.
(Let the switches be called A, B and C)
- Turn on the switch A.
- Turn if off after a minute.
- Now turn on the switch B.
- Open the door and go in.
(There should be no delay between the above steps unless specifically mentioned)
By looking at/feeling the lamp you can tell which switch is connected to it.
If the lamp is lit -> it's the switch B.
If the lamp is not lit, but warm -> it's the switch A.
If the lamp is not lit and also cool -> it's the switch C.
p.s. - Assuming that the lamp used is the kind that uses filament and becomes hot while operational. mOrpheuSitch B.
[*]Open the door and go in.

That makes perfect sense, I should of said that because Im always burning my hand on the lamps at home XDflip them all and open the door. Unless you have some wierd wired thing, you should be able to turn the light on
Correct!Thats the correct answer!You get 2Frih for it.!Well done morpheus!
