(OT) How did those old gas station bells work?

Same thing for road lane vehicle counting machines which cops put out in place to place from time to time. Air works just fine.

When the car rolled over the hose it collapsed the wave function and a muon was fired down the hose. The round thing at the end of the hose, mounted on a wall usually, accelerated the muon to super luminal speeds at which point thousands of leptons were released and when they hit your head, it made you think there was a ringing sound due to the observer effect.
