Nitrous oxide (N 2 O), commonly referred to as laughing gas, along with various street names, is an inert gas which can induce euphoria, dissociation, hallucinogenic states of mind, and relaxation when inhaled. [1] Nitrous oxide has no acute biochemical or cellular toxicity and is not metabolized in humans or other mammals.
Inhaling directly from a cracker is particularly dangerous due to the risk of developing frostbite on the inside of the mouth or esophagus. [5] [6] The 8 gram nitrous oxide steel cylinder charger when discharged into an empty whipped cream dispenser creates a pressure of 30 pounds per square inch (200kPa) and delivers 3.24 litres of nitrous ...
An IMR smokeless powder for reloading The Hagley Museum in Wilmington, Delaware. IMR Legendary Powders is a line of smokeless powders which are popularly used in sporting and military/police firearm cartridges. The initials 'IMR' stand for Improved Military Rifle powder. IMR powders makes a line of various types of smokeless powder suitable for ...
Nitrous oxide is a colourless gas with a faint, sweet odour. Nitrous oxide supports combustion by releasing the dipolar bonded oxygen radical, and can thus relight a glowing splint. N 2 O is inert at room temperature and has few reactions. At elevated temperatures, its reactivity increases. For example, nitrous oxide reacts with NaNH

[3]: 287–289 Nitrocellulose produces greater volumes of gas per volume of solid than black powder does, so nitrocellulose bulk powders were less dense than later smokeless powders. Nitrocellulose bulk powders designed for early straight-sided black powder rifle cartridges like the .32-40 and .38-55 were friable and easily crumbled. The ...
The combustion products of smokeless powder are mainly gaseous, compared to around 55% solid products (mostly potassium carbonate, potassium sulfate, and potassium sulfide) for black powder. [1] In addition, smokeless powder does not leave the thick, heavy fouling of hygroscopic material associated with black powder that causes rusting of the ...
The .577 BPE originated around 1870 with the 2 1 ⁄ 2-inch variant. [1]The 3-inch cartridge has survived to the current day as the .577 Nitro for Black, the same cartridge loaded with mild loadings of modern smokeless powder, carefully balanced through trial to replicate the ballistics of the Black powder version.
