Three lightbulbs.

Thu May 01, 2008 1:36 am  by Sxc Shadow

You are standing outside a basement door, Down the stairs, there are 3 light bulbs.

Next to you, are 3 switches. You cannot see the lights from upstairs, and you must decide which switch controls which lightbulb by going downstairs once.

How do you do this?

Turn on first switch, leave it on for a few minutes. Then turn it off and flip second switch.

When you go into the basement, the first switch is the bulb that is off, but hot. The second switch is the bulb that's on. The thrid switch is the bulb that's cold and off.
