Gunpowder was first created by Chinese alchemists in the 9th century as a result of their quest for an elixir of life, and was originally composed of potassium nitrate, charcoal, and sulfur. It was primarily used for fireworks until the 10th century when it saw its first military applications in rocket propelled arrows used against the Mongolians. When combusted, gunpowder will deflagrate instead of detonate, producing enough force for a bullet to be shot from a weapon without rupturing the barrel. It remained a Chinese monopoly until the 13th century when it began spreading to Europe and the Middle East via the Silk Road, where it was mainly used in cannons before being incorporated
Stainless steel are a range of alloys containing at least 10.5% chromium.
Stainless steel is widely used for roofing, cladding, interior and exterior trim owing to its combined strength and low maintenance.
The corrosion resistance of iron-chromium alloys was first recognized in 1821 by French metallurgist Pierre Berthier, who noted their resistance against attack by some acids and suggested their use in cutlery. Metallurgists of the 19th century were unable to produce the combination of low carbon and high chromium found in most modern stainless steels, and the high-chromium alloys they could produce were too brittle to be practical.
Stainless steel is available in square, rectangular and circular hollow section as well as the standard section for structural work.

10 innovations you thought were new (by @creaxnv)CREAX
New innovations are not always as groundbreaking as you might think. Very often innovation is simply the result of continuous evolution and not that radical at all. We listed 10 innovations and show that some of them date back to more than 100 years ago.
The nail gun was invented in the early 1900s when an Englishman experimented with using explosive powder to drive fasteners. This led to the development of an early powder-actuated tool used for stunning cattle. In the 1940s, an American developed a more practical powder-actuated nail gun called the Velocitool. In the late 1940s, another company created the first compressed air nail gun. Today after many refinements, nail guns are a common power tool used in construction.
This document provides information on different types of firearms and their mechanisms. It describes how cannons, pistols, machine guns, and torpedoes work. Cannons use gunpowder to propel cannonballs by the combustion of gunpowder creating pressure. Pistols use triggers to release hammers that ignite gunpowder and propel bullets. Machine guns use different loading mechanisms like magazines or belts to rapidly fire ammunition. Torpedoes are self-propelled underwater weapons that use guidance systems and explosives to target ships. The document aims to educate while cautioning safety with firearms.
World War II saw countries developing secret and unusual weapons. [1] Britain proposed an aircraft carrier made of pykrete, a wood pulp-reinforced ice mixture that was bulletproof. The project was abandoned due to the massive refrigeration needs. [2] The Soviet Union attempted to attach wings to tanks, but the project was cancelled because airborne tanks lacked armor. [3] The U.S. made explosive pancakes coated in flour that could pass as food to sabotage Japanese supply lines. Tallboy bombs could tunnel underground to collapse Nazi bunkers from within. Many strange ideas were attempted but never fully realized due to practical limitations.

The document provides a history of the development of firearms from early hand cannons to modern systems. It describes the major innovations in ignition mechanisms from matchlock guns to flintlock guns to percussion caps. Important developments included the wheel lock mechanism, snaphaunce, muzzleloaders, Colt's revolver, breechloaders, and the introduction of cartridges using rimfire, pinfire, and centerfire systems. Modern firearms are categorized based on their bore, loading, firing, and handling characteristics.
Fullerenes are carbon allotropes composed entirely of carbon in hollow spherical, ellipsoid, or tubular structures. In 1985, Kroto, Curl, and Smalley discovered buckminsterfullerene (C60) through molecular beam experiments that observed discrete carbon molecule peaks, including at 60 atoms. C60 is named after geodesic dome architect Buckminster Fuller due to its similar structure. Fullerenes have applications as polymer additives, in carbon nanotubes used for strong, conductive materials like tennis rackets and aircraft composites, and in molecular pumps and nanowires for electrical motors and light bulbs.
World War I was caused by rising nationalism, imperialism, and shifting alliances between European powers. It lasted from 1914 to 1918 and resulted in over 10 million military deaths. Though weapons had advanced significantly, military tactics had not evolved to counter new technologies like machine guns and artillery. Mass infantry formations were decimated on the modern battlefield, where indirect fire and chemical weapons caused widespread casualties. The stalemate of trench warfare ensued, with neither side able to gain a decisive advantage.
Carbon has 8 main allotropes including diamond, graphite, fullerene, carbon nanotubes, and amorphous carbon. Diamond is the hardest known mineral that forms in a cubic crystal lattice. Graphite is soft and used in pencils as it forms in hexagonal planes. Fullerenes like C60 buckyballs were discovered in 1985 and are hollow spherical structures that can be used in nanotechnology. Carbon nanotubes are stronger than diamonds and can conduct heat well. Amorphous carbon is found in coal and soot and does not have a defined crystal structure. The different allotropes of carbon have a variety of applications including industrial uses, electronics, medicine, and more.
The document provides a history of firearms, beginning with early projectile weapons like bows and arrows during the Stone Age. It then discusses the invention of gunpowder around 1260 and the earliest portable firearms known as "handgonnes" in the late 14th century. Subsequent sections describe the development of matchlock guns in the 15th century, wheel lock guns in the 16th century, snaphaunce and flintlock mechanisms, and culminates with modern percussion, pinfire, rimfire and centerfire cartridge systems.

The document provides information on various forming processes including rolling, extrusion, shearing, spinning, deep drawing, and forging. It describes the basic principles, key advantages, common materials used, and brief histories for each process. Rolling is used to reduce thickness and increase length of materials like metals. Extrusion forces pre-heated material through a die to form a constant cross-section. Shearing uses blades to make straight cuts in sheet metal. Spinning forms tubular parts by stretching sheet material against a rotating form. Deep drawing stretches sheet metal into cups or pans using a punch and die. Forging shapes heated metal using dies or hammers to develop strength.

24. Hydrogen(All of which was just listed is more expensive than Hairspray but more explosive)Ignition-So when you ignite it after spraying it in the back end of the potato cannon it will explode inside of the firing chamber and force the potato out at extraordinary speeds.
25. Solvent Welding Solvent Welding- Solvent welding is the process of joining articles made of thermoplastic resins by applying a solvent capable of softening the surfaces to be joined, and pressing the softened surfaces together. Adhesion is attained by means of evaporation of the solvent, absorption of the solvent into adjacent material and /or polymerization of the solvent cement.
26. BLACK POWDER What is Black Powder- basic black powder is made of 75% potassium nitrate, 15% charcoal, and 10% sulfur. These ingredients are ground to create a uniformly textured powder. How did Black Powder come out-By the 9th century Taoist monks or alchemists searching for an elixir of immortality accidentally stumbled upon gunpowder. What Black Powder is used for- Black Powder is used in all kinds of things in the 19th and 20th century, such as- Cannons, Guns (muskets), and any sort of bomb. (And there were millions of guns and cannons). A simple, commonly cited, chemical equation for the combustion of black powder is 2 KNO3 + S + 3 C -> K2S + N2 + 3 CO2. A more accurate, but simplified, version is 10 KNO3 + 3 S + 8 C -> 2 K2CO3 + 3 K2SO4 + 6 CO2 + 5 N2.
