Phosphorus-Ignited Molotov Cocktail
Carton: Length, 13 1/2 inches; diameter, 3 1/2 inches.
Bottle: Length, 9 3/4 inches; diameter: 2 1/8 inches.
Igniter capsule: Length, 3/8 inch; diameter, 2 1/8 inches.
Weights:
Grenade (complete): 2 pounds 12 ounces.
Bottle (filled): 1 pound 10.5 ounces.
Inflammable liquid: 9.5 ounces.
Igniter capsule (complete): 2 ounces.
Igniter compound (black phosphorus): 1 ounce.
Filling: 15 percent solution of polymethyl-methacrylate in benzene.

Description: The grenade consists of a 300 cc. green or clear glass bottle with an in-flammable liquid and sealed with an ordinary crown type cap. The bottle is fitted with an adjustable rubber harness which is used to hold a flat circular glass igniter capsule to the base.

The grenade is packed in a tubular varnished cardboard carton. The igniter capsule is well protected in the container by several layers of cardboard and saw-dust.

Operation: A rip cord is pulled to open the carton. The igniter capsule is secured to the base of the bottle by the rubber harness. When the grenade is thrown forcibly against a hard target it shatters and the friction between the pieces of phosphorus causes instant ignition of the inflammable material. The viscous nature of the filling prevents undue splashing and insures adherence to the target.
