Flash bang grenades were designed to stun people. But they have a pretty bad safety record. The little bombs have dismembered at least one soldier and caused hearing loss in others.
To remedy that problem, Mark Grubelich and his colleagues at Sandia National Laboratory built the Improved Flash Bang Grenade. It hurls flaming aluminum particles into the air, causing a bright flash without an accompanying shockwave.
