Schrödinger‘s Coin

Schrödinger’s Coin

This switch was designed with the “Schrödinger’s Cat” inquiry in mind. Except a cat doesn’t carry enough electricity in it to complete an electrical circuit. This could be a paperweight for the science nerds, it could just be an inside joke. The positive end of the battery is connected to an aluminum foil pad with an alligator clip. The negative end of the battery is connected to an LED, followed by a series of resistors. The resistors are connected to a second aluminum pad. The circuit is incomplete until a coin is placed on the two aluminum pad, connecting the two side of the circuit.
