Lemonade - A good use for life's lemons

some wise guy in England has set up a "young people repellent" - something called a "mosquito" - read a BBC piece about it This "mosquito" thingy emits a shrill annoying noise that is audible to only the young ... the irritating noise is supposed to keep the trouble-making teenagers and other young people away

Note: It is "SUPPOSED" to keep the young away ... but no one told the young about this supposedly intended purpose ... so, the young have put the mosquito noise to good use ... this economist piece points out

British teenagers have already shown how the table can be turned. Using mobile phones to record the silent-to-many output of the Mosquito machines they have used the sound to disrupt classes by irritating fellow students while teachers remain oblivious. And in schoolrooms, where mobiles are banned, the sound is a useful semi-private ringtone. In an already noisy world an arms race of sound is not to be welcomed.
