Most residential fire extinguishers are trivial to refill if you have a pipe wrench and an air compressor. Medium sized commercial ones are even easier, since many of them have recharging valves on them, and many of those are actually just the same as a regular Schrader tire valve.
You can just grab the entire valve assembly with a pipe wrench or even clamp it in a vise and give it a good twist and you’ll find that it unscrews. The majority of modern fire extinguishers are filled with some kind of fine powder, which you can either dump out or, if you are starting with a fire extinguisher that’s already been expended, there will be very little of it left in there anyway.
Fill the extinguisher’s cylinder with your payload to about halfway full. You need some air space at the top for your propellant. Unless you are such a dedicated and well equipped nut that you probably didn’t need instructions in the first place, your propellant will be compressed air.
Bung the valve back on the cylinder and if you’re lucky it’ll have a recharge valve and you can just pump it up like a tire. Watch the pressure gauge on the side. Get it in that green zone in the middle and you’re good to go. If your extinguisher isn’t the type intended to be recharged, no worries. Get a blowgun with a rubber nozzle on it and press it into the nozzle on the fire extinguisher, hold the valve open, and inflate it right through the outlet with your air compressor’s blowgun. The latter method may cause a small amount of backblast of whatever you filled the thing with, so don’t do this if you filled it with anything really nasty and either way preferably do it outside.
It probably doesn’t work as well as a commercial refill (which I believe for most models is done with liquid CO2) but it absolutely will dispense most of whatever you used to refill it with alarming volume and velocity. Most extinguishers can dispense either liquid or powders, regardless of what they were originally filled with…

Do try make compostable glitter? Or is that just dirt.
Mica flakes, maybe. Certainly not compostable, but at least found in nature in quantity.
And stupid dangerous to get in the eye. Like most things, though, I guess. Fuckem.
Glitter fire extinguisher instructions for repelling chuds are what the internet was made for
I miss the old times when this was true - the internet held such possibility and promise.
…I really hope this yearning for a lost time isn’t the catalyst for my mental facilities to decay into chud-dom.
