3 Lights
In the basement there are 3 lights switches in the off position. Each switch controls 1 of 3 light bulbs on the floor above. You may move any of the switches, But you may only go up stairs one time. How can you determine which switch controls each light?

Turn any one switch to the 'ON' position for approximately five minutes.
Then turn that switch 'OFF'. Then turn any other switch to the 'ON' position and run up stairs. Feel the two lights that are 'OFF'. One of them should feel 'HOT' because it was 'ON' for about five minutes. The hot bulb is controlled by the first switch that was turned 'ON'. The light that is currently 'ON' is controlled by the switch you last turned 'ON'. The 'cold' bulb that is 'OFF' is controlled by the only switch left ?
