The lunch bag incendiary is similar in size and effect to the pocket incendiary used by the Office of Strategic Services OSS) in World War H It consists of a sandwich-sized slab of soap napalm and an ignition packet scaled in a zip-lock sandwich bag. It fits in a pocket, purse, or pack and is easy to handle. 

To prepare, clean and dry a square, half-gallon milk carton. Pour in 4 cups of fuel and 2 tablespoons of denatured alcohol. Mix well. Add 2 1/2 cups of soap powder or 3 1/2 cups of soap flakes. Stir until it begins to thicken, approximately 15 minutes. Seal the carton with tape and let it sit for 2 days. The mixture will thicken into a firm buttery paste. Chill for an hour in the refrigerator, remove, and carefully peel off the milk carton. Cut the resulting block into 1-inch slabs and place them in individual sandwich bags. Double wrap to help contain the fumes. 

It may seem somewhat puzzling that in the case of a slab of material surrounded by vacuum—a model for a soap film—the film feels a tendency to become thinner. This can be explained by the notion that a molecule in the film is surrounded by fewer other molecules than a molecule in the bulk. It, therefore, has a higher potential energy in the film than in the bulk and tends to move from the film to the bulk liquid. 

The first theory for film fluctuations resembles Cahn s theory of spinodal decomposition of unstable bulk systems. A very simple mechanism was adopted for the liquid flow. It was assumed that because of the presence of the soap monolayers, the film surfaces were stagnant (see Section 11) and that the film liquid was pumped back and forth through a slab with thickness h according to Reynolds s law ...

Mode of Preparation.—Olive oil is boiled with caustic soda (sodium hydrate) glycerin passes into solution, and sodium oleate (hard soap) floats on the surface of the liquid. After remaining quiescent for a few hours the soap [is skimmed off, transferred to frames, in which it solidifies on cooling, and finally cut by wires into slabs or bars.

A wooden box, receives the from the machine. The bar or slab of soap, being placed on the inclined plane, e, is allowed to touch the cutter the handle being now turned, the first blade removes a shaving, and is immediately followed by the second blade, and so on until the entire bar is cut, when it is replaced by another, and so quick is the operation, that in an hour two cwt. of soap may be reduced to shavings by this useful machine. 

Chitting the Soap.—When the soap is sufiBciently cold it is cut into slabs and bars proportionate to the size required for the tablets, which generally run eight, six, four, or two to the pound. The bars are next divided into cakes or blocks, the width of which is regulated according to the size and weight of the tablets. 

It is important to note that in practice the wire diameter must be taken into account because it forms a slab of liquid composed of two soap films. Hence the work required is ... 

The blocks of soap should not be stripped until quite cold throughout, and they should be allowed to stand open for a while before slabbing. When freshly cut into tablets, the soap may appear somewhat turbid, but the brightness comes with the exposure it will receive prior to stamping and wrapping. 

The length of time the soap should remain in frames is dependent on the quality, quantity, and season or temperature, and varies usually from three to seven days. When the requisite period has elapsed, the sides and ends of the frames are removed, and there remains a solid block of soap weighing from 10 to 15 cwt. according to the siise of frame used. The blocks, after scraping and trimming, are ready for cutting into slabs. 

All tallow soaps should be slabbed whilst still warm, out into bars, and open-piled immediately if this type of soap is cold when slabbed its appearance will be very much altered. 

They are applied on roofs, slabs on ground, basements, water-retaining structures, concrete blocks, and clay bricks. Waterproofing admixtures reduce the permeability of concrete. The dampproofing admixtures impart water repellency and reduce moisture migration by a capillary action. Examples of these admixtures are soaps and fatty acids which react with cement, conventional water reducers, methyl siliconates, etc. 

The DLVO theory can be used to analyse foam stabilization by electrostatic repulsion. When a substance is added to a foam leading to the charge of the surface film this can result in the repulsion of the air bubbles coming near to one another. Soap (surfactant) films arc modelled by two air slabs (infinite thickness) with a liquid film in between. The attractive potential is then given by ...
