Dynamite is an explosive based on the explosive potential of nitroglycerin using diatomaceous earth as an adsorbent.
It is usually sold in the form of a stick roughly eight inches (20 cm) long and one inch (2.5 cm) in diameter but other sizes also exist.
Dynamite is considered a "high explosive", which means it detonates rather than deflagrates.
The chief uses of dynamite used to be in construction, mining and demolition.
However, newer explosives and techniques have replaced dynamite in many applications.
Dynamite is still used, mainly as bottom charge or in underwater blasting.
