Today, velocity of detonation can be measured with accuracy. Together with density it is an important element influencing the yield of the energy transmitted for both atmospheric over-pressure and ground acceleration. By definition, a "low explosive", such as black powder, or smokeless gunpowder has a burn rate of 171–631 m/s. [15]
This is a compilation of published detonation velocities for various high explosive compounds. Detonation velocity is the speed with which the detonation shock wave travels through the explosive.
It provides a great balance of stability and power, and is the composition used in most commercial exploding fireworks. The balanced equation for the reaction is:- 3 KClO 4 + 8 Al → 3 KCl + 4 Al 2 O 3. The stoichiometric ratio is 34.2% aluminum and 65.8% perchlorate by mass.
Pyrotechnics is the science and craft of creating such things as fireworks, safety matches, oxygen candles, explosive bolts and other fasteners, parts of automotive airbags, as well as gas-pressure blasting in mining, quarrying, and demolition.
The operation was by far the largest-known illegal fireworks operation, and the initial blast was heard as far away as 20 miles (32 km) from the site. [17] Both operations were connected to a multi-state illegal fireworks distribution and production ring, and multiple people were eventually sent to prison for their involvement in both incidents.

Explosion of unserviceable ammunition and other military items The explosion of the Castle Bravo nuclear bomb.. An explosion is a rapid expansion in volume of a given amount of matter associated with an extreme outward release of energy, usually with the generation of high temperatures and release of high-pressure gases.
