Dynamite is an explosive material that was invented in 1867 by Alfred Nobel. It is made from nitroglycerin, a highly volatile liquid, which is absorbed into an inert substance like diatomaceous earth to stabilize it. This makes dynamite safer to handle compared to pure nitroglycerin. Dynamite is commonly used in construction, mining, and demolition to break rock or clear land. When detonated, it produces a powerful shockwave that can move large amounts of earth or debris. Its effectiveness and relative safety have made it a popular choice for various industrial applications.
