Get off of my lawn..........and my sidewalk.
Store's don't like it when a bunch of kids gather outside the entrance and I don't like it when a bunch of skateboarders are zinging up and down my sidewalk. Here is a deterrent.
BBC: A device emitting a soundwave which is designed to drive young troublemakers away from a problem area of Swindon has been hailed as a success. Listen to the sound online.
I only hear some noise.
The 'Mosquito' sonic deterrent device...the sound resembles that of a buzzing insect. And it works by emitting a harmless ultra sonic tone that generally can only be heard by people aged 25 and under. In trials, it has proven that the longer someone is exposed to the sound, the more annoying it becomes.
There is a simple solution to get rid of kids that are annoying. Stick a speaker in the window and blast this at them. They scatter in a few minutes.
