Dynamite!

In 1863, Alfred Nobel invented the Nobel patent detonator or blasting cap for detonating nitroglycerin.

Nitroglycerin was first invented by Italian chemist Ascanio Sobrero in 1846. In its natural liquid state, nitroglycerin is very volatile. Alfred Nobel understood this and in 1866 he discovered that mixing nitroglycerine with silica would turn the liquid into a malleable paste, called dynamite.
