A commonly cited example is a report of the Battle of Mohi in Eastern Europe that mentions a "long lance" sending forth "evil-smelling vapors and smoke", which has been variously interpreted by different historians as the "first-gas attack upon European soil" using gunpowder, "the first use of cannon in Europe", or merely a "toxic gas" with no ...
Still, black powder remains in use for certain types of firearms, including historical weapons from before the invention of smokeless powder, such as muzzleloaders. Black powder substitutes are propellants designed to provide explosive force similar to that of black powder, primarily for use in such firearms, despite being legally classified as ...
Gunpowder, an explosive mixture of sulfur, charcoal and potassium nitrate (also known as saltpeter), was the original propellant employed in firearms and fireworks.It was used from about the 10th or 11th century onward, but it had disadvantages, including the large amount of smoke it produced.
A 1682 demonstration of Huygens gunpowder engine, where a dram of gunpowder creates enough vacuum to lift 8 boys into the air. Huygens, however, became interested in the mechanical power of the vacuum, and the possibility of using gunpowder to produce one. In 1678 he outlined a gunpowder engine consisting of a vertical tube containing a piston ...
A prepared anvil. Gun powder is in a chamber between the anvils and visco fuse. Typically, two anvils are used: one as a base (placed upside down), and another one (also known as the "flier") as the projectile (placed right-side up, atop the base). [3] An alternative method is to place the bottom anvil upright, and fill the hardy hole with ...
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.
Also the fuse, at times, protrudes from the ends of these firecrackers, as opposed to the middle of the tube in real M-80s. Genuine M-80s have paper endcaps, and contain slightly more powder. Contrary to urban legend, an M-80 that contains 3,000 mg of powder is not equivalent to a quarter-stick of dynamite.
Not to be confused with earlier incendiary arrow projectiles, the fire arrow was a gunpowder weapon which receives its name from the translated Chinese term huǒjiàn (火箭), which literally means fire arrow. In China a 'fire arrow' referred to a gunpowder projectile consisting of a bag of incendiary gunpowder attached to the shaft of an arrow.
