The extinguishers automatically trigger if a piece of film near the gate starts to burn. A training film for projectionists included footage of a controlled ignition of a reel of nitrate film, which continued to burn even when fully submerged in water. That tragedy claimed 123 lives during the fire and additional fatalities several days later, when hospitalized victims died due to inhaling excessive amounts of smoke from the burning film, which was laced with toxic gases such as sulfur dioxide and hydrogen cyanide. 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. Like association croquet, the object of the game is to be the first to pass each of their balls through all six hoops in both directions and to strike the central peg, for a total of 26 points. And number 9-15 are striped balls. In this case, the shooter can only aim at object balls that are directly on or on the opposite side of the head string.

And that’s why you might have felt that one of the two types of balls was smaller than the other. While it might seem like there’s plenty of room for a pool table, it’s vital to accurately assess the space. PET, like cellulose mononitrate, is less prone to stretching than other available plastics. Nitrate dominated the market for professional-use 35 mm motion picture film from the industry's origins to the early 1950s. While cellulose acetate-based safety film, notably cellulose diacetate and cellulose acetate propionate, was produced in the gauge for small-scale use in niche applications (such as printing advertisements and other short films to enable them to be sent through the mails without the need for fire safety precautions), the early generations of safety film base had two major disadvantages relative to nitrate: it was much more expensive to manufacture, and considerably less durable in repeated projection. 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.

The manufacturing process was not properly understood and few safety measures were put in place. If you’re a somewhat experienced player, you may be able to tell just by shooting a few balls. 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. Whenever someone dies, they are sent to one of many mysterious bars run by bartenders serving as arbiters inside a tower in the afterlife. But that is only the case when other balls are small.- When both balls are of the same size, there is no leverage or loss. For one thing, the balls in the playfield will not stand out as starkly as they would on a brighter felt - especially the 8-ball. The last thing anyone wants is to blow the game-winning shotbecause the final ball was camouflaged!

In carom billiards games, when all the balls are kept near each other and a cushion so that with very soft shots the balls can be "nursed" down a rail, allowing multiple successful shots that effectively replicate the same ball setup so that the nurse shots can be continued almost indefinitely, unless a limit is imposed by the rules. Even two groups of players shooting pool at two adjacent tables can be playing by different rules. Adding other kinds of games is trivial provided that they can be played on the existing tables (snooker for example requires some more work). Polyester is much more resistant to polymer degradation than either nitrate or triacetate. Disastrous fires related to celluloid or "nitrate film" became regular occurrences in the motion picture industry throughout the silent era and for many years after the arrival of sound film. Cinema fires caused by the ignition of nitrocellulose film stock commonly occurred as well. In that year alone, five very destructive fires occurred at four major studios and a film-processing plant. 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.
