'What can someone do with an old fire extinguisher?' was my question of the day.

First some facts:
- I love hacks
- I've got such a thing at home
- I never dismantled such a thing before
- I'm a peaceful guy who didn't want to make another air cannon or rocket launcher
- I lost my expensive hightech multicoated swissmade drinking bottle on my last kayaktrip at sea

One thing led to another and so I decided to make my customized drinking bottle.

Hope you like it as much as I do!

Step 1: Exit fire extinguisher - the safe way

The concept of a fire extinguisher is simple: an aluminium canister filled with very fine chemical powder and a valve connected to a small cartridge with pressurized carbondioxide or air.
Once you removed the safety pin and you pushed the handle aka valve, the gas is released into the canister and the powder is blowing out.

To obtain the hardware you'll have to dismantle it.
There are two ways:
- or you descrew it all (for a new extinguisher the best method)
- or you empty it the fire-extinguish-way to set free the pressure (the safest way to do so is upside down in a bucket with water, this will prevent the powder blowing out everywhere)

Since I wasn't sure that my extinguisher had been used or not, I put it in the water, pushed the valve and... nothing happened!
All the gas was already gone (in case of a fire I wouldn't have been very happy). So I descrewed it, emptied it and cleaned all the parts with a lot of boiling water.
I stored the powder in my garage - it still can be used!
I really like the aesthetic of the bottle. For some reason, it brings about an industrial/modern feeling, and the use of a fancy fire extinguisher that utilizes technology and chemicals to put out flames to ultimately store the basic fire extinguishing compound—water—for drinking is really cool too.
unless you KNOW that was a sodium bicarb extinguisher... they use some nasty stuff in many of the dry-chemical models. <br> <br>The Bottle of the one I have is straight up aluminium, with the paint removed. <br>Putting MINE on the stove boils water just fine. <br>YOURS may or may not. <br>Personally, I would worry about the paint burning(red= lead? at least if it was made in china) but the bottle SHOULD be fine. Heck you can boil water in a PAPER CUP. <br>The only issue I could see is, afterward, the bottle will become soft and easily dented. <br> <br>Fun factoid... if you make/have an adapter, you can fill the bottle with water, replace the mechanism, pressurize it, and have a super stealth watergun for summer fun(or dousing the last of that pesky camp fire before bed).
Hi ironman, <br>My bottle was made in Belgium. I contacted the manufacturer and they assured me it was a sodiumbicarb type extinguisher. This stuff is absolutely harmless (a few weeks ago I did a lot of it on my fries, confusing it with table salt - I'm still alive still kicking). <br>Thanks for the advice &amp; tips and you know, it's much nicer to pee that fire out!
Chemicals was my first thought, totally forgot about sodium-bicarb extinguishers.
Hiya - good hack. <br> <br>Bugger might sink if ya drop it in the drink but she aint never gonna break - good job. <br> <br>Probably keeps your drink really cool too.
Thanx mate! Kept in an old sock the drink should stay on temperature!
I would be very concerned with residual chemicals in the bottle &amp; with putting water in the un-lined aluninum (leaching)- I'll pass on this one ...
Since friday my neighbour's dog is only drinking from this bottle. If he's still fine in a week or two I will drink from it my own. <br>I'm just wondering if he was already waggling before I started the experiment or not. You think I should disturb my neighbours on their holiday for this?
