I know the solution to this one, so you have likely all heard it:
You start in a hallway.
There is a door to a room, the room is about five cubic feet.
In the room is a lightbulb.
The room has only walls, a ceiling, a floor, a door and a lightbulb.
The room is such that you cannot see if there is light coming from the room except by opening the door.
In the hallway are 3 lightswitches (typical switches, up for on, down for off), all off.
Only one switch operates the lightbulb.
You can only open the door once, the switches can only be operated before opening the door.
You cannot disassemble the switches or any goofy $hit like that.
How do you determine which switch operates the bulb?
Hi g514, welcome to the forum. It is good to see you posting, I will be back with the answer if no one comes up with it. However, that is a very remote possibility.
Switch one switch on for a few minutes, then turn it off and put the next one on and open the door, if the light is on it is that one, if it is not on feel the bulb to see if it is warm if so it is the first switch, if not it is the remaining switch.
I like that riddle, alot.
