A contact explosive is a chemical substance that explodes violently when it is exposed to a relatively small amount of energy (e.g. friction, pressure, sound, light). Though different contact explosives have varying amounts of energy sensitivity, they are all much more sensitive relative to other kinds of explosives.
This light is equivalent in energy to some of the stabilization energy of the energy for the chemical reaction, i.e. the bond energy. This light that is released can be absorbed by other molecules in solution to give rise to molecular translations and rotations, which gives rise to the classical understanding of heat.

In technical terms, the reaction zone (chemical combustion) is a self-driven shock wave where the reaction zone and the shock are coincident, and the chemical reaction is initiated by the compressive heating caused by the shock wave. The process is similar to ignition in a Diesel engine, but much more sudden and violent.
The violent chemical reaction ignited the detonator and exploded the mine. The mine did not have a safety or anti-tamper mechanism. Disarming one was a fairly simple procedure of unscrewing the igniter near the base, avoiding the fragile top. [4]
In simple terms, the 'Barking Dog' reaction is a combustion process, in which a fuel (carbon disulfide, CS 2) reacts with an oxidizing agent (nitrous oxide, N 2 O), producing heat and elemental sulfur. The flame front in the reaction is a zone of very hot, luminous gas, produced by the reactants decomposing. 8 N 2 O + 4 CS 2 → S 8 + 4 CO 2 ...
