Wow....it's a great IQ test. Try to get ur answer! XD
2dayblog: An IQ test here for you all – John is in a big mansion and he needs to match out the three switches located on the top floor for the three light bulbs located at the ground floor (not visible from top floor) but he can only get down once to check out the bulbs. No other devices were used, only hands. More details: There are 3 switches on the top floor - switch A, switch B and switch C and they were used to switch on the 3 light bulbs located at the ground floor. John needs to find out the switch for each of the bulbs but he can only get to the ground floor once to check the bulbs. - Nothing tricky. - Nothing to do with the wiring. - John is alone in the mansion. - No other devices were used for the checking. - The switches are normal type which can only be on/off. The question is ~ How John managed to know which switch goes to which light bulb by getting down once only. It is a test from a friend. Do you guys know the answer? Comment please.

Turn a switch on for a while. Then turn it off. Then turn the second switch on and go into the room. The one that is warm, is the first one that was on for a while and the other two are obvious as one is on and one is off.
