Here's a riddle for ya. There's a house with two levels. You're facing three switches in a room in the lower level. One of the switches controls a light bulb in a room in the upper level. If you plan to go up the stairs only one time, how would you determine which switch controls the light bulb.

Sidenote: There's no way you can look into the upper level room from downstairs.



This is actually more of a creative thinking exercise than a riddle. I learned of this in one of the R&D classes back in poly where the lecturer used it to tell us about paradigms and mindsets. "Think in more than one dimension" he said. No, i wasn't supposed to go for the class, but i stole into the lecture room. I'm after all the bandit :)
