Liquid Explosives
An explosive material, also called an explosive, is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material.
This potential energy stored in an explosive material may be
- chemical energy, such as nitroglycerin or grain dust
- pressurized gas, such as a gas cylinder or aerosol can.
- nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239
Explosive materials may be categorized by the speed at which they expand. Materials that detonate (explode faster than the speed of sound) are said to be "high explosives" and materials that deflagrate are said to be "low explosives". Explosives may also be categorized by their sensitivity. Sensitive materials that can be initiated by a relatively small amount of heat or pressure are primary explosives and materials that are relatively insensitive are secondary or Tertiary explosives.

Famous quotes containing the word liquid:
“Telephone poles were matchsticks, put there to be snapped off at a whim. Dogs trotting across the road were suddenly big trucks. Old ladies turned into moving—vans. Everything was too bright, but very funny and made for my delight.
