Experiment - Generating electricity from heat

  You can try this experiment at home also. Take any two different wires ( made up of different metals or non-metals, like copper and steel ). I used a copper wire and a nail made up of steel. Take the copper wire, and round it along one side of the nail. More rounds ( loops ), means more electricity. Connect the other end of the copper wire and the other end of the nail to an LED or a motor or any other objects like that. Take the side of the nail, rounded with copper wire, near to a candle flame ( CAUTION : Don't bring very close to the flame, or else the wire can burn) or any hot object. You can see the LED glowing, or the motor rotating.
