Q: You are in a house and you see three switches on the wall. The sign says only one of these switches turns on the upstairs light. You may go upstairs only once to check and see. How can you find out which switch by going upstairs only once?

A: You turn the first switch on for five minutes then turn it off. Then you turn on the second switch and go upstairs. If the bulb is on it is the second switch. If it is off but hot it is the first switch. If it is off and  cold it is the third light. (from Marcie and Phil)
