Here’s an article that I found hilarious. I truly do hope that one of my students tries this. Especially since staring at your hands inside your purse is not obvious at all.
Recently, in classes at Trinity and elsewhere, some students have begun testing the boundaries of their new technology. One place was Michelle Musorofiti’s freshman honors math class at Roslyn High School on Long Island.
At Roslyn, as at most schools, cellphones must be turned off during class. But one morning last week, a high-pitched ring tone went off that set teeth on edge for anyone who could hear it. To the students’ surprise, that group included their teacher.
“Whose cellphone is that?” Miss Musorofiti demanded, demonstrating that at 28, her ears had not lost their sensitivity to strangely annoying, high-pitched, though virtually inaudible tones.
“You can hear that?” one of them asked.
“Adults are not supposed to be able to hear that,” said another, according to the teacher’s account.
She had indeed heard that, Miss Musorofiti said, adding, “Now turn it off.”
The cellphone ring tone that she heard was the offshoot of an invention called the Mosquito, developed last year by a Welsh security company to annoy teenagers and gratify adults, not the other way around.
It was marketed as an ultrasonic teenager repellent, an ear-splitting 17-kilohertz buzzer designed to help shopkeepers disperse young people loitering in front of their stores while leaving adults unaffected.
The part that I really like is that was designed as a teenager repellant. Can you imagine some old Welsh guy, upset about the Queen Mum, walking around blasting kids?
I picture him in an old green jacket and a cabbie hat. Cackling.

I always wonder if people think I have too much time on my hands.
And then I see something like this and feel better.
And this is pretty cool.
