The Banana Switch: Never be in doubt you're eating a banana!

                                       

 

My switch uses a slightly browning banana as a switch for the circuit. The positive part of the circuit was stabbed into the banana, for maximum security for the jumper. The other end is on the stem of the banana, and leads back to the start of the circuit. Most people probably don’t know that the banana is about as conductive as your finger, depending on how moist the inside of it is. Due to the conductivity of this banana, who’s insides have begun to slightly mush, the current is able to pass through with relative ease to help power the LED.
