Shopkeepers in England, annoyed by adolescents loitering around their stores, are installing a new device called the Mosquito. It emits an ultra-high pitched annoying noise—“eeeeeeeeek”–that people over 25 cannot hear. It drives away the kids while adults, with their deteriorating hearing, remain unphased.

But still, isn’t the Mosquito a great invention? Don’t you just want one? I can imagine many other uses. I wonder if Mosquito technology could be applied to all boom-boxes and car stereos, once the windows are opened, so that only young people could listen to their music despite their good-hearted impulse to share it with the rest of us.
