Generic Bomb by the Jolly Roger
Acquire a glass container 
Put in a few drops of gasoline 
Cap the top 
Now turn the container around to coat the inner surfaces and then evaporates 
Add a few drops of potassium permanganate (<-Get this stuff from a snake bite kit) 
Throwing against a solid object detonates the bomb. 
*AFTER THROWING THIS THING RUN LIKE HELL THIS THING PACKS ABOUT 1/2 STICK OF DYNAMITE*
