Fifteen-ball Billiards was Developed in America

Yet again, on June 13 in Philadelphia, a fire and a series of explosions ignited inside the 186-square-meter (2,000-square-foot) film vault of the Lubin Manufacturing Company and quickly wiped out virtually all of that studio's pre-1914 catalogue. Millions of feet of film burned on March 19 at the Eclair Moving Picture Company in Fort Lee, New Jersey. Today, nitrate film projection is rare and normally highly regulated and requires extensive precautions, including extra health-and-safety training for projectionists. Those additions intended to prevent or at least delay the migration of flames beyond the projection areas. The use of volatile nitrocellulose film for motion pictures led many cinemas to fireproof their projection rooms with wall coverings made of asbestos. Goodwin's patent was sold to Ansco, which successfully sued Eastman Kodak for infringement of the patent and was awarded $5,000,000 in 1914 to Goodwin Film. During the year 1914-the same year that Goodwin Film was awarded $5,000,000 from Kodak for patent infringement-nitrate film fires incinerated a significant portion of the United States' early cinematic history. Later that same month, many more reels and film cans of negatives and prints also burned at Edison Studios in New York City, in the Bronx; then again, on May 13, a fire at Universal Pictures' Colonial Hall "film factory" in Manhattan consumed another extensive collection.

Even after film technology changed, archives of older films remained vulnerable; the 1965 MGM vault fire burned many films that were decades old. Safe and sustained production of guncotton began at the Waltham Abbey Royal Gunpowder Mills in the 1860s, and the material rapidly became the dominant explosive, becoming the standard for military warheads, although it remained too potent to be used as a propellant. Guncotton manufacture ceased for over 15 years until a safer procedure could be developed. The British chemist Frederick Augustus Abel developed the first safe process for guncotton manufacture, which he patented in 1865. The washing and drying times of the nitrocellulose were both extended to 48 hours and repeated eight times over. That fire, a catastrophic one, what is billiards started inside a film-inspection building and caused over $7,000,000 in property damages ($213,000,000 today). In the meantime, George Eastman had already started production of roll-film using his own process. Direct matter propulsion. Same method as above, just using gigantic mass drivers/railguns to fire huge quantities of matter away from Earth, instead of a rocket exhaust. The projector is additionally modified to accommodate several fire extinguishers with nozzles aimed at the film gate.

For this reason, immersing burning film in water may not extinguish it, and could actually increase the amount of smoke produced. As a projectile driver, it had around six times the gas generation of an equal volume of black powder and produced less smoke and less heating. The game is played with 22 balls, made up of one white ball (the cue ball), 15 red balls, and six numbered coloured balls including one yellow 2, one green 3, one brown 4, one blue 5, one pink 6, and one black (valued at 7 points). But there is more to pool than the traditional billiard game. The good news is that setting up a pool table in a garage doesn’t have to be costly or overly complicated. There are plenty of garage floor coverings available. In football you run your hardest and kick your hardest, and few spectators are much the wiser; and a nervous man can always hit hard at golf off the tee and through the green, for as he has not got to think of strength, he is less likely to fidget and foozle the ball. The manufacturing process was not properly understood and few safety measures were put in place.

Schönbein collaborated with the Frankfurt professor Rudolf Christian Böttger, who had discovered the process independently in the same year. The patent rights for the manufacture of guncotton were obtained by John Hall & Son in 1846, and industrial manufacture of the explosive began at a purpose-built factory at Marsh Works in Faversham, Kent, a year later. In his From the Earth to the Moon, guncotton was used to launch a projectile into space. The power of guncotton made it suitable for blasting. Jules Verne viewed the development of guncotton with optimism. By coincidence, a third chemist, the Brunswick professor F. J. Otto had also produced guncotton in 1846 and was the first to publish the process, much to the disappointment of Schönbein and Böttger. Guncotton was originally made from cotton (as the source of cellulose) but contemporary methods use highly processed cellulose from wood pulp. In 1855, the first human-made plastic, nitrocellulose (branded Parkesine, patented in 1862), was created by Alexander Parkes from cellulose treated with nitric acid and a solvent. In 1868, American inventor John Wesley Hyatt developed a plastic material he named Celluloid, improving on Parkes' invention by plasticizing the nitrocellulose with camphor so that it could be processed into a photographic film.
