I am inspired by the classic “Bomb Disposal” actions in movies to use plier as the switch of LED. One has to cut the wire in order to light up the LED instead of pressing or sliding something.
So I came with the dangerous idea of play with the short circuit. I connected three LED with the button battery and then use another wire to connect the positive and negative part of the battery to make a short circuit.
When cutting the wire that connecting different sides of the battery, the short circuit will end and the circuit will back to work again.
