From Popular Science's article on scary weapons comes another bright idea by the Military-Industrial Complex--the folks who gave us the gay bomb.
This time it's the Puke Light.
...the flashlight uses ultra bright, rapidly pulsating LEDs to first temporarily blind and then induce nausea and sometimes vomiting. The pulses quickly change color and duration, which can cause psychophysical effects in many people...
Haven't they ever heard of "puke and rally?"
Fortunately, the article concludes that the pukelight "is a promising tool for non-violent enforcement." So remember to be careful the next time y'all decide to flee a Dennys or something.
