Sonic Nausea is a small electronic device which can really turn one's stomach. It generates a unique combination of ultra-high frequency soundwaves which soon leads most in its vicinity to queasiness. It can also cause headaches, intense irritation, sweating, imbalance, nausea, or even vomiting. Hiding this device in your inconsiderate neighbor's house might put an end to their late-night parties. The abusive bureaucrat's office, the executive lunchroom... the possibilities are endless for that small portion of inventive payback. The unique soundwave characteristics make directional source determination difficult. Powered by one 9-volt battery (not included). For extended run time six AA batteries in a battery pack with transistor clips (available from most electronics stores) can be used instead. Use with extreme discretion.
