Rubber Chicken Parking Sensor
Parking sensors are proximity sensors for cars and are designed to alert a driver if they’re too close to an object like another car, a parking meter or a tree using ultrasonic or electromagnetic sensors. But this person didn’t need any fancy gadgets. They simply taped a rubber chicken to their bumper, which screeches when it gets squeezed. It may not be as sophisticated as a conventional parking sensor, but it will do the job.
