(True story...)
When we were in high school, one of the guys found a book about how planes used to drop "chad", or squares of metal, to block radar during WWII. We all had gotten speeding tickets in a radar trap by Kennedy airport.
So, this guy rigged a spring-loaded box, with a cable-release, to the front of his '61 Chevy. We spent one night cutting about a thousand 1-inch squares of aluminum foil. We all jumped in the car, and ran the radar trap at about 70 mph, releasing the foil about 500 feet before the trap.
....well, we got pulled over by NY's Finest... the cop asked "..just what in the hell was that all about?" The driver sheepishly explained the concept.
The cop thought it was the funniest thing he ever heard...
...gave him a pass on the speeding, but issued a $100 fine for Littering.
...chad don't work.
