Outside a room on the wall are three numbered light switches that operate three light bulbs inside the room. The door is solid with no window in it.
Is it possible to identify which switch operates each bulb ? You may only enter the room ONCE after doing whatever you want with the switches and you can only touch TWO of the three switches.
THE ANSWER

Switch on number 1 switch, leave for a minute, then turn off. Then switch on number 2, and walk into the room. The light that is on obviously is worked by switch 2, climb onto something and feel the other two bulbs, the one that is warm is operated by 1 and the other by 3
