Well, this is a revolting development. Now some dweeb can carry around a $29 device that literally makes you sick. Sure, we've seen a lot of gadgets that make us sick, but this one does it for real. As the story goes, you simply attach this tiny circuit board to a 9-volt battery, and suddenly everyone within about 30 feet starts getting that seasick feeling, maybe even spontaneously throwing up. Yuck.

Whether its ultra-high frequency sound waves really work is not quite certain, but we have heard of the military dabbling in sound emitters that can cause nausea, immediate bowel evacuation, or even liquefy living flesh. So maybe this inner-ear-tweaking thingamajig could work. That said, please, young pranksters who like to secretly use gadgets that cause controversy, don't bring one of these to CES.
