Acetylene Arrow

The Acetylene Arrow is one of Green Arrow’s oldest toolbox tricks. An acetylene welding/cutting torch burns at the tip of the arrowhead. This trick is most often used as a handheld tool, but in emergencies it can be fired as an extremely lethal arrow with a 6000° F arrowhead.

It can’t burn for a terribly long time given the limited amount of fuel in there. This one may be the basis for the Safecracker Arrow.

Reality Check

Pure acetylene (C2H2) is a colorless and odorless gas. Acetylene is the primary fuel for oxy-fuel welding torches. It’s the fuel of choice for repair work and general cutting and welding.

Combined with oxygen, acetylene urns at 5800 °F to 6300 °F (3200 °C to 3500 °C), highest among commonly used gaseous fuels. Acetylene’s primary disadvantage as a fuel in comparison to other fuels is high cost.

Acetylene can be used in water, but it is unstable at a pressure roughly equivalent to 33 feet underwater. Water submerged cutting and welding is usually reserved for hydrogen rather than acetylene.
