Picture of POCKET FIRE EXTINGUISHER
everyone wants to feel safe and secure. many people keep pepper spray, tasers, knives, and all sorts of other self defense items with them at all times. these are great against a human attacker or dogs and other animals, but what if the elements themselves turn against you. what will your taser do against a fire??? nothing. luckily now, with the pocket fire extinguisher, you can feel safe from the elements everywhere you go.

this instructable will teach you how to make an effective pocket sized fire extinguisher so that you can feel prepared at your next candlelight dinner.

Step 1: How It Works

fires need oxygen to burn. if you can smother the fire, then it will go out. to do this out extinguisher uses a combination of dry powder and co2. we will use a simple co2 canister to shoot blasts of co2 at the fire, but it will also blast baking soda into the fire, which when heated produces co2. attacking the fire from two fronts

Step 2: What You Need

to build this extinguisher you will need several things:

+ a co2 canister (16g is good) THREADED
+ an old bike tube
+ some tape
+ scrap metal, or a spoon of some sort
+ some foam (for insulation)
+ a co2 canister bike adapter (see foot note)
+ baking soda (NOT BAKING POWDER)
+ a small container with fastening lid (holds baking soda)

FOOT NOTE: i had one of these nifty things lying around in one of my bike kits, but if you dont have one you can find them at most bike stores or online here: http://www.amazon.com/Genuine-Innovations-133111-Microflate/dp/B001K0LXPA/ref=sr_1_7?ie=UTF8&s=sporting-goods&qid=1247662324&sr=1-7
ignore the bad review, mine worked great for inflating tires. (and for putting out fires)

I think the candle is a bad example. It would blow out. But I take your word for it! Nice Job!

Tip for shooting close-up photos: turn on macro; it enables you to take clear close-up photos.

online you can get them fairly cheap. and any biking shop will carry them, also any place that sells airsoft will usually have them
