A 12-year-old school boy who was fed up with people nicking his lunch has invented a clever lunchbox alarm system to catch out his thieving classmates.
Nic James, from New Zealand, was so sick of seeing his lunch disappear he fitted a siren alarm into his drink carton.
He carries around a stereo which is tuned to the same FM frequency as the siren. When the box is opened, the siren goes off, and it blares out of Nic's stereo.
'Heaps of burglaries'
He was driven to invent the lunch alarm because there had been "heaps of burglaries in bags and stuff."
And his clever invention came third in the 'kitset modification' category of the Bright Sparks competition in Australia.
But according to the Daily News, he was very humble about his prize.
In fact, he didn't want to make a meal of it (groan!).
