That there is a prank device that generates a combination of sound waves calculated to make a person physically ill.
Sonic technology as a weapon isn’t anything new to the world. Sonic weapons have been in development for years for nonviolent alternatives to forceful crowd control. But this “pranking device” is only barely nonviolent, because it causes headaches, vomiting, and loss of balance.
You might think this would be something only riot police used, but that’s not the case. In fact, if you have about 40 dollars to spend, it can be purchased in minutes. That’s a little bit of a scary thought because it means anybody who has worked a job for about 5 or 6 hours can go online and cause some pretty hardcore nausea to those who cross him or her.
It works by generating a series of combined soundwaves that make you physically ill. So if you’ve got some money laying around and think giving someone terrible nausea would be a kick, you can go buy one at any number of online retailers.
