	Acetylene is a very reactive gas, with an unusually wide range of flammability, 2.5 to 82%, in air. It can decompose spontaneously with no air present if the pressure of the gas exceeds just 15 psi. It is more prone to [[detonation]] than any other gas except perhaps hydrogen. Acetylene also has an extremely low ignition energy, and even the static charges developed in plastic pipes can ignite it.

	The potentially destructive power of acetylene comes from the extremely rapid release of energy that creates very high pressure spikes. Acetylene can create slightly higher pressure levels than propane, but the hazards associated with acetylene make it ~~unuseable~~ in spudguns. Acetylene is particularly hazardous in [[~~hybrids~~]].		The potentially destructive power of acetylene comes from the extremely rapid release of energy that creates very high pressure spikes.

'''Acetylene''' (chemical formula C2H2) is a flammable gas used for welding and cutting. It is far too powerful for a spudgun, and its use can result in injury or death. There are also dangers that are unique to acetylene, because the molecule contains an unstable and energetic triple bond that is easily broken.

Acetylene is a very reactive gas, with a flammability limit of 2.5 to 100% in air. It can decompose spontaneously with no air present, if there is an ignition source, or simly if the pressure of the gas exceeds 15 psi. Because of this it is more prone to [[detonation]] than any other gas. Acetylene is also very sensitive to static electricity, and it comes out of the tank dry which means that plastic materials containing the cas get charged easily.

In addition to these dangers, the gas doesn't even contain as much energy per volume as [[propane]], it's gross calorific value is 56000 kJ/m2 as opposed to propne's 101000 kJ/m2. The destructive power comes from the extremely rapid release of energy, which creates very high pressure spikes.
