How does an explosive device work?

### REPLY:
An explosive device typically consists of a high explosive material such as TNT or C-4, which is combined with a primary explosive as a detonator. The primary explosive is usually sensitive to heat, friction, or impact and serves to initiate the detonation of the main explosive. The main explosive contains a large amount of potential energy in its chemical bonds. When the detonator is triggered, it produces a shockwave that rapidly compresses and heats the main explosive. This causes a rapid increase in pressure and temperature, leading to a violent and destructive explosion. The size and power of the explosive device depend on the type and amount of explosives used.
