NO GOOGLING OR SEARCHING THE INTERNET FOR THE ANSWER!!!

RIDDLE: You are standing in front of a room with one lightbulb inside of it. You cannot see if it is on or off. Outside the room there are 3 switches in the off positions. You may turn the switches any way you want to. You stop turning the switches, enter the room and know which switch controls the lightbulb. How?

    It's the switch inside the doorway.

    I've seen the light
    I can't quite figure out which switch to twitch but I'd guess you can tell by the temperature of the bulb somehow.
    Maybe turn switch 1 and 2 on, leave #3 off.
    Wait a minute or two then turn switch #2 off.
    Go in the room and see if the light is on. If it is then it's switch #1, if not see how hot it is. If it's warm it's #2, if it's cold then it's #3 since it would not have been turned on.


    Sort of like that magic trick where you have everyone examine a penny, then put in into a hat and pull out the "right" one because it's warmer than the others/

    Yes, you have.
    Very clever solution, Phil.

    I think from thinking and
    I think from thinking and seeing Phil's guitar picture of early 1970s that the answer my friend is blowing in the wind, the answer is blowing in the wind.
