ABSTRACT:
An anti-shark grenade which comprises concentric tubes of lightweight plastic, the outermost tube being a waterproof shell on the inside of which are located a plurality of percussion caps bearing against a waterproof tube containing an explosive charge fitting against a tube containing dehydrated blood cake bait and having a water permeable perforated closure. The innermost tube is a buoyancy tube sealed at both ends. Water causes the blood cake to dissolve thereby attracting the shark to the floating grenade. Upon biting by the shark, the grenade explodes.
