You are in a room with 3 switch which control 3 lightbulbs in the other room. There is no window and there is 1 door. You can only go in the other room one time and once you open the door you must go in and the door will close behind you. You must find out which switch controls which lightbulb, how do you do it?

Flip one switch (from here on, "switch 1"), wait 10 mins, turn it off.
Flip another switch (from here on, "switch 2") and leave it on.
Go in the next room.
The bulb that is off, but warm is connected to switch one. The one that is on is connected to switch 2.
The bulb that is off but cool to the touch is connected to switch 3.
