Built on the same principles as the larger versions used to disperse crowds, this tiny Sonic Nausea device generates a combination of high frequency soundwaves which will cause most people in its vicinity to feel queasy or suffer from headaches, intense irritation, sweating, imbalance, nausea and if you’re really lucky, even vomiting! The nature of the sound means it’s very difficult to pinpoint where it’s coming from if hidden, and I’m going to assume on a single 9-volt battery it will run for many, many hours. $29 from Shomer-Tec.
