A few years later in 1838, another French chemist, Théophile-Jules Pelouze (teacher of Ascanio Sobrero and Alfred Nobel), treated paper and cardboard in the same way. H. G. Wells wrote The Croquet Player which uses croquet as a metaphor for the way in which people confront the very problem of their own existence. Salvaging old films is a major problem for film archivists (see film preservation). Related fires in other medical facilities prompted the growing disuse of nitrocellulose stock for X-rays by 1933, nearly two decades before its use was discontinued for motion-picture films in favour of cellulose acetate film, more commonly known as "safety film". Acetate film manufactured during the era when nitrate films were still in use was marked "Safety" or "Safety Film" along one edge in dark letters. Many films produced during the early 20th century were lost through this accelerating, self-catalyzed disintegration or through studio warehouse fires, and many others were deliberately destroyed specifically to avoid the fire risk. 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. In 1929, several tons of stored X-ray film were ignited by steam from a broken heating pipe at the Cleveland Clinic in Ohio.

The film was also used for many years in the field of medicine, where its hazardous nature was most acute, especially in its application to X-ray photography. Guncotton manufacture ceased for over 15 years until a safer procedure could be developed. While guncotton is dangerous to store, the hazards it presents can be minimized by storing it dampened with various liquids, such as alcohol. We can see that after many bounces, the trajectory of the ball converges to the horizontal. A chaotic system will also move predictably towards its attractor in phase space - but instead of points or simple loops, we see "strange attractors" appear - complex and beautiful shapes (known as fractals) that twist and turn, intricately detailed at all possible scales. Then a second fire hit the Edison Company at another location on December 9, at its film-processing complex in West Orange, New Jersey. Practice English first without object balls, and then with object balls. The rack is the triangular frame used to arrange the object balls in a specific pattern before the break shot. Yes, the sound of a solid crack from a good break in billiards is the sound of a good fifteen to twenty minutes of fun getting started.

The origins of billiards date back to the 15th century in Europe. I also met Anthony, the other owner of the very recently opened bar (and Billiards hall), but it was Albert behind the bar this afternoon chatting with my buddy and I over a couple of beers and a delicious "Wiz Wit". 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. During the first World War, British authorities were slow to introduce grenades, with soldiers at the front improvising by filling ration tin cans with gun cotton, scrap and a basic fuse. Today, the Dryden Theatre at the George Eastman Museum is one of a few theaters in the world that is capable of safely projecting nitrate films and regularly screens them to the public.

A special projector certified to run nitrate films has many modifications, among them the chambering of the feed and takeup reels in thick metal covers with small slits to allow the film to run through them. Projection rooms may also be required to have automatic metal covers for the projection windows, preventing the spread of fire to the auditorium. The use of volatile nitrocellulose film for motion pictures led many cinemas to fireproof their projection rooms with wall coverings made of asbestos. The use of nitrate film and the looming threat of its fiery potential were certainly not issues limited to the realm of motion pictures or to commercial still photography. 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. In the meantime, George Eastman had already started production of roll-film using his own process. Nitrocellulose was used as the first flexible film base, beginning with Eastman Kodak products in August 1889. Camphor is used as a plasticizer for nitrocellulose film, often called nitrate film.
