Comparison To Explosives
Though both news reporters and black-market dealers often make comparisons between the power of salutes and a particular quantity of dynamite ("1/4 stick" or "as powerful as a fourth of a stick of dynamite"), such comparisons are not grounded in reality. For reference, a typical stick of dynamite contains over 10 times more explosive material than an M-80 (35 grams of nitroglycerin versus 3 grams, typically of chlorate/sulfur powder). Nitroglycerin explodes with a shockwave faster than the speed of sound, whereas the powders used in various salutes deflagrate (burn) at a slower rate and below the speed of sound. This distinction is the difference between High Explosive and Low Explosive.
More to the point, dynamite undergoes detonation whereas flash powder in any quantity undergoes deflagration. Because flash salutes do not generate a detonation wave, they have a very low brisance and they do not exhibit the Munroe effect. For this reason, salutes are unsatisfactory for initiating the detonation of blasting agents.

Famous quotes containing the words comparison to and/or comparison:
“In comparison to the French Revolution, the American Revolution has come to seem a parochial and rather dull event. This, despite the fact that the American Revolution was successful—realizing the purposes of the revolutionaries and establishing a durable political regime—while the French Revolution was a resounding failure, devouring its own children and leading to an imperial despotism, followed by an eventual restoration of the monarchy.”
—Irving Kristol (b. 1920)
“From top to bottom of the ladder, greed is aroused without knowing where to find ultimate foothold. Nothing can calm it, since its goal is far beyond all it can attain. Reality seems valueless by comparison with the dreams of fevered imaginations; reality is therefore abandoned.”
—Emile Durkheim (1858–1917)
