Pupils perform ‘alarming’ feat | Metro.co.uk
:
A high-pitched alarm which cannot

schoolchildren to create ringtones so they
can get away with using phones in class.

Techno-savvy pupils have adapted the
Mosquito alarm, used to drive teenage
gangs away from shopping centres.

brilliant cooptation of the technic’s purpose.
