For example, liquid oxygen is an oxidizer and is usually stored in its liquid state at a very low temperature. Because liquid oxygen has a very large liquid-to-gas-expansion ratio, 1 to 860 at 68° f, it can undergo an explosion known as a boiling liquid expanding vapor explosion, commonly referred to as a bleve.

But you've probably heard of one liquid explosive already -- nitroglycerin. Nitroglycerin was invented in 1847, and it's made by adding acids to glycerin. Since exposure to it dilates people's blood vessels, it's used as a medical treatment for angina pectoris, or heart pain. Nitroglycerin is made of carbon, nitrogen, hydrogen and oxygen.
