... The Napalm in question belongs to the U.S. Navy, Southwest Division, Naval Facilities Engineering Command. They currently store this "Vietnam era" Napalm at the Navy's Weapons Support Facility in Fallbrook, California. Fallbrook is approximately 60 miles north of San Diego. The inventory consists of about 34,000 aluminum canisters packaged in individual wooden crates. The canisters contain a total of 23,000,000 lbs. of Napalm or 3.3 million gallons. (Napalm is composed of [46%] polystyrene, [33%] gasoline and [21%] benzene.)
About the best fire bomb is napalm. It has a thick consistency, like jam and is best for use on vehicles or buildings.
Napalm is simply one part gasoline and one part soap. The soap is either soap flakes or shredded bar soap. Detergents won't do.
The gasoline must be heated in order for the soap to melt. The usual way is with a double boiler where the top part has at least a two-quart capacity. The water in the bottom part is brought to a boil and the double boiler is taken from the stove and carried to where there is no flame.
Then one part, by volume, of gasoline is put in the top part and allowed to heat as much as it will and the soap is added and the mess is stirred until it thickens. A better way to heat gasoline is to fill a bath tub with water as hot as you can get it. It will hold its heat longer and permit a much larger container than will the double boiler.
Improvised Napalm
In talking about this, I have found that there are many ways to this wonderful substance. My favorite is by mixing gasoline and styrofoam. Usually in a metal can. Keep adding the styrofoam until the mix is very stinky, an then add a little bit of kerosine. Another method is by taking a double boiler, filling the bottom portion with approx 3/4 full of water. Put either gasoline or kerosine into the top. Add pure SOAP chips to the mix. Heat the fuel until it boils and then simmers. Stir constantly until the desired consistency is reached: remember that it will thicken further on cooling. Last we come the 'Soldier' technique, anyone who saw this movie will recognize this one. Carefully heat the end of a 100 watt light bulb. again-carfully remove the metal end and internal parts. Fill the glass bulb with half gasoline. and then 1/4 more with dish washing liquid. Finally take rubber cement and glue the two parts back together. Be sure that you put enough mixture into the build so that the metal wire is well submerged before use and during.
