Bike Lock Makes Thieves Immediately Vomit

Someone decided to make a bike lock that shoots out a gas when it’s cut. Uh, what happens when there are other people around it? My solution was to just buy a bike that didn’t cost hundreds of dollars.

With his co-inventor, Yves Perrenoud, Idzkowski created a U-shaped lock of carbon and steel with a hollow chamber to hold one of three pressurized gases of their own concoction, including one called "formula D_1". When someone cuts about 30% of the way into the lock, Idzkowski said, the gas erupts in the direction of the gash. "It’s pretty much immediately vomit inducing, causes difficulty breathing," Idzkowski said. "A lot of similar symptoms to pepper spray." The inventors have not yet tested the device on an actual would-be thief, but have tested it on themselves and volunteers at distances of two feet (60cm), five feet, 10ft and 20ft. "At two feet it was pretty bad. It was absolutely vomit inducing in 99% of people.
