Bad news, bad guys: the US Dept of Homeland security has developed a flashlight that'll make you sick. Literally. The light uses an array of ultrabright LEDs that flash in a way that'll induce nausea, making people barf all over the damned place.

Gross, right? But hey, if you had a choice between getting shot or throwing up everywhere, which would you choose? That's what I thought. Just another example of creative ways to take people down without actually hurting them, which I, for one, am all for. Just don't let the barf light get into the wrong hands, I.E. anyone but cops. That's the last thing we need to have popping up at parties. — Adam Frucci
