How do you make a homeade fire extingusher?
406266
Depends on the type of fire you're extinguishing.  For wood and paper fires (type A), any container of water will do.  For flammable liquids (type B) or electrical fires (type C), a water-based extinguisher is a very bad idea.  I'm not quite sure if or how you could make a homemade carbon dioxide extinguisher or dry chemical extinguisher.  I suppose you could imitate a dry chemical extinguisher with any non-flammable item/substance and smother the fire.

Hi\nYou can just use a simple plastic water,drink or juice bottle.\n\nIMPORTANT NOTE:your rocket may not work if you use a screw lid.\n\nTo make rocket:\n1 Tape a straw to the side of the bottle:make sure that one end of the straw is within 1-2cm of the top of your bottle\n\nTo make launch pad:\n1 Insert skewer into a round piece of cardboard so that the skewer is standing securely upright.\n\nTo launch rocket:\n1 Insert one of the following fuels:\n   1x crushed alka-selzer tablet and 15ml of water \n   1 teaspoon of baking soda and 40mL of vinegar.\n2 Then put on the lid on as soon as the substance(s) are in the rocket.\n3 Place rocket on launch pad so that the skewer goes through the straw.\n4 watch in amazement as your rocket takes off!

Make Your Own Gelled Alcohol Fuel - Canned Heat\n \nExtreme do it yourselfers can make their own gelled fuel at home with by mixing alcohol and calcium acetate (C4H6CaO4).\n \nThe following instructions and measurements are from the Montville High School Science Departmental.\n \nAdd 25g of crushed chalk or egg shells (calcium carbonate-CaCO3) to 100ml of vinegar (water and acetic acid - CH3CO2H) and stir for about 5 minutes.\nThis should produce carbon dioxide (CO2), calcium acetate (C4H6CaO4) and water (H2O) plus leave you with some left over chalk (CaCO3).  If you are guessing on how much chalk to add, just make sure that there is a little extra after 5 minutes of stirring.\n \nRemove the excess chalk by filtering your mix through some filter paper (coffee filter or napkin can be used).\nSet a funnel in a jar, place your filter in it and pour your suspension through it.\n \nMark the level of your solution in its container and allow your solution to evaporate off about half that volume to remove the excess water.\nPlace your solution in an oven set on low heat or place it out in the sun to dry.  If you went to far - just add the missing water.\nNote - if you like, you can dry out your solution completely and store the remaining dried calcium acetate for future use.\n \nIf your solution isn't already in the container you want your gel in, then pour it in there now.\n \nAdd 30ml of alcohol (ethanol, methanol, or isopropanol) to your solution and watch the gel form.  Do not stir.\n \nOnce the reaction in complete, pour off any extra fuel.\n \n \nY2kSurvivor suggests:\nDissolved calcium acetate solution ratio:\n1 part dry calcium acetate (by volume) to 2 parts water\n \nSolution to fuel ratio:\n1 part dissolved calcium acetate solution to 4 parts alcohol\n \nAlso see:\nCanned Heat: Alcohol Gels - University of Wisconsin\nCanned Heat An Alcohol Gel - Chem Matters\nCanned Heat: Sterno - Normal Community High school

This is how to do it, I have done it 1 month ago in school.\n\nMaterials Needed:\n1)Plastic Soda/Water/Juice Bottle.\n2)Liquid, you have to fing the correct combination of liquids to use, and see which liftoff was the best and try to be creative, don't blow yourself or your house up, though.(we did at school)\n3) I believe it is a pumper, you could search it online as "water bottler rocket launcher" on Yahoo. I THINK it's around $60:)\n4) materials you want to decorate your rocket with(leave the inside empty)\n\n\nInstructions:\n1)Decorate your bottle, don't make it too heavy though.\n2)Find the best liquids that mix to make the rocket's liftoff better, or buy it from someone(remember to buy it legally).\n3)Mix the liquids, be safe and don't blow up anything.\n4)Insert the liquid in the hollow bottle, and immediately insert the top(the side you drink with) in the whole, make sure the launcher you buy fits the size of your bottle.\n5)Push the red(or any other color button), the rocket might start to shake, that it OKAY.\n6)Let an ADULT, hold the string, and count down.\n7)The string is jerked, and the rocket is lifted off.\n\nRemember, these instructions might vary from launcher to launcher, and to be safe when mixing liqiuds, mix safe liquids like orange juice and apple juice!\n\nAnd be safe..............

Throw some live coals on 'em, and a pint or so of unleaded.  Stand nearby with a hose.  Make sure you do this away from things you care about.

You need something called a fire wall.  You can download a very good one at zone labs.  It's free...

Coming from a SFX background I can tell you the best and cheapest way is to use a basic fog machine with fog juice (1part glycerin 3 parts distilled water) This will produce a cloud of fog. \n\nFor it to hug the ground you need what is called a fog chiller. \n\nEasy to make.\nUse a rub washer to connect the output of the fog machine to a copper tube that runs into an ice chest and makes a coil shape through ice water (or dry ice) then comes out the other side. As the glycerin steam cools to a temp below the room temp it will hug the ground.\n\nGuaranteed to work.

My freind Kyle knows how to do this. He had his own at one point.  But he isnt online right now. Im really sorry.. but if you keep this question open for a bit I can get back to you on this. \n\nHe just came online.. and im really sorry but he says it's very hard to explain! I really wish I could help though :(

Fill the bottle with water but not completely full and using a bike pump fill the bottle with air while aiming it where you want it to go; and you just keep pumping the air in until it fires.\n\nI suggest you build some sort of mount so you aren't holding the bottle when it goes off. I also suggest you try different sized bottles and different amounts of water.

Make one that shoots mini marshmallows.\n\nMy dog loves them, but the larger ones are too messy in the summer when they are not consumed, and they start melting on the walkway.

The trap should have two block valves, a vent and a drain valve.\n\nClose the two block valves. Open the vent valve to relieve the pressure and then the drain valve to remove any liquid. Opening the drain valve first can cause the pressure from the trap to stir up any dirt and rocks that might be in the area causing a spark and possible fire. \n\nYou should also have on hearing protection when this is done because the noise from the vent valve can be quite high.\n\nLeave the vent and drain valve open while you remove the end closure.

If you are referring to a flaming arrow as lighting a campfire ... here you go:\n\n**The Powered Flaming Arrow**\n\nThis next variation is a much more complex, but much cooler. It can be done in an area where the closest tree is up to 200 yards away. \n\nConstructing this modified version takes a while longer, but if it is set up correctly, it is well worth the effort. \n\nFor this version you will need to use some kind of wire instead of kite string. This is a little more expensive, especially if you need a couple hundred feet. Using insulated wire works better than bare metal. \n\nTake your wire and fasten it onto a stake in towards the back of the fire ring. Run the other end up into a tree making sure that the wire is clear of branches. \n\nNow the fun part, take a flare, a dowel, a model rocket engine (size B or C), and some duck tape. With this assemble a unit where the dowel is taped above the flare, and the engine behind the dowel. Once you have made some kind of assembly (make sure the flare is pointing forwards and the engine is pointing backwards) cut 3 pieces of the wire into about 4 inch segments. Make a loop in the middle, and fasten the 3 loops to the flare assembly making sure you put the loops on the main wire first. \n\nTie a string to the flare and pull it up into the tree. Now put an ignitor in the engine and hook it up to a battery ignitor. Now you are ready to build your fire. Remember to put plenty of dry tinder so it will easily catch when the dowel hits. Suggestionfor use - a bag of pine shaving hampster litter. \n\n*Hint: Have the dowel extend out past the flare so when it hits the stake in the fire pit it protects the flare from snuffing out. \n\nWhen the participants arrive have one person up in the tree ready with a lighter to light the flare. The MC of the fire should have some kind of script like, "I call upon the spirits of the trees to send forth a ball of fire to light our fire!" This can be adapted and modified to make it more special and magical. Once this is said, the flare is to be lit, wait a few seconds, and ignite the engine. If all this is done correctly your flare should come speeding into the fire ring, it will be dark for a few seconds, then your fire will come alive.

Assuming you mean in a vacuum.\nAs long as you could create a delivery system that would spray both the oxidant and the combustive material in a constant stream it would work.  The problem is that if you are spraying both the chemical accelerant and the oxygen it needs to burn from the same appliance, you have to be careful that one of both of the chemicals don't mix inside the delivery mechanism or the fire will follow the path and explode inside the device.\nNASA has torches and similar devices for welding but they are extremely short range (inches).  The flame wouldn't look like one here on Earth as any particles that strayed from the main spray of oxident would immediatly stop burning.\nAlso, you wouldn't be able to cause any other combustable things to burn once the flame was removed.  If you concentrated it on a piece of wood, for instance, it would burn until you pulled the "flamethrower" away and would immediately stop burning.

Wow.  There are only several thousand recipes.  You can do this over a camp fire, on the stove, in a steamer or crockpot.  Either just throw in what you like or, if you are one of those "by the book" people use one of the sites below to find a recipe:
