Steampunk Weapon: P.H.R.E.D.D.

Description

P.H.R.E.D.D. (Pronounced “Fred.”) Pneumatic Hypergolic Reaction Enigma Disposal Device

Everyone knows that vampires are vulnerable to wooden steaks. But what you may not know is that a wooden bullet is just a teeny, tiny wooden steak. Likewise, salt, a purifying mineral, is able to help dispose of pesky poltergeists, and werewolves are repelled by mistletoe. They’d be so useful as ammunition, however, all of these items would be destroyed by the explosion caused by typical gunpowder.

And that’s where P.H.R.E.D.D. comes in! This gun uses the power of pressurized steam to launch its projectiles, preventing the ignition or melting of more fragile ammunition!

Initially, glycerin is loaded into the backmost tank, while potassium permanganate is poured into the reservoir in the main body of the gun. Meanwhile, the topmost canister is filled with water.

The first pull of the trigger will load a specified amount (as regulated by the component adjustment knobs) of these two chemicals into the water canister, where a hypergolic reaction occurs, resulting in steam. This canister is within a larger one, where the steam collects and pressurizes. When the pressure reaches a certain level, a small door inside moves, allowing the steam to go into the second compression chamber (the rapid depressurization of the first chamber cools it off enough to be safe. However, if the temperature spikes too high, there is a pressure release switch that will vent the steam before the gun overheats) The rushing of steam spins tiny turbines, generating a small electrical charge, enough to cause little lights to turn on, indicating that the weapon is ready to be fired.

When the trigger is pulled the second time, it releases the extremely compressed steam into the barrel, propelling the projectile toward its target, be that projectile a bullet or magic scroll.

Happy Hunting!


This is my first prop gun mod, and yes: this started out life as a super soaker. It’s part of my Steampunk Little Red Riding Hood Cryptozoologist costume (the same one I built the Lycanthrope Case for), but I liked it so much, I wanted to make the gun itself a separate deviation.

I like the idea of it alot, good job on this! Nice to see an actual explanation for something Steampunk instead of just "steam, ingenuity, gears, and whim". I bet this can actually be made in real life!
