and let me tell u .........i used to show magic to 4th standard students using a capacitor...........

first i will charge the capacitor using a battery ,behind the stage.then i used to bring an LED and connect it to the capacitor.all the students were astonished to see the LED glowing witout a battery.(they dont know abt capacitors...........hahhaahaha).

but after glowing the LED came the real trouble.............since its not possiable to make it glow too long(charge stored is very less),the bulb start to unglow slowly..................
but i managed to end the show before it get OFF.........
