A man in New Orleans, USA, developed a method to prevent thieves from breaking into his car by rigging a flashbang to detonate if someone broke in. A flashbang is an explosive device that triggers a temporarily blinding flash of light and a loud noise. Such devices stun and disorient people who are nearby.
