YouTuber's glitter bomb tricks parcel thieves
A former Nasa engineer spent six months building a glitter bomb trap to trick thieves after some parcels were stolen from his doorstep.
The device, hidden in an Apple Homepod box, used four smartphones, a circuit board and 1lb (453g) of glitter.
Mark Rober, who is now a YouTuber, caught the original thieves on his home security camera.
He decided to take action after the police said they were unable to investigate the case.
He designed the elaborate bomb so that it would be activated when the package in which it was hidden was opened by thieves. The phone cameras and microphones would record the moment.
The device contained an accelerometer to detect motion.
When the parcel was jostled, the device would check the GPS signal to see if it had been moved from its spot.
If it had, then it would send a signal to activate the phones and start recording.
The glitter was in a cup that spun round on a motor when released as the box was opened.
The device was also engineered to squirt a tube of strong-smelling fart spray every 30 seconds.
