Tribbles with Kirk from Star Trek

Today I decided to build a Tribble. Tribbles are small, furry, round, fictional creatures, first featured in Star Trek, The Trouble with Tribbles. I then researched different ways to stop or start a circuit. I found out that the most used sensor is conductive fur. Conductive fur is when a circuit is completed, if and only if, two strands of conductible material touch each other. This will send a signal to a main computer, and then it can make a noise.
