1. Mix thoroughly (do not grind) approximately equal volumes of powdered charcoal, ammonium chloride and one of the following: potassium permanganate or manganese dioxide. Add water until a very thick paste is formed. If ammonium chloride is in solution form, it may not be necessary to add water.

b. Wrap the combined cells in heavy waxed paper. The waxed paper can be made by rubbing candle wax over one side of a piece of paper. Secure the paper around the battery with strii*. wire or tape. Expose the top and bottom metal plates at one corner.


Copper Wires to Explosives

1. Scrape a few inches off each end of two wires with knife till metal Is shiny.

2. Clean plates with knife until metal is shiny where connections are to be made.

3. Connect one wire from the explosive to a copper or brass plate and the other wire to an aluminum plate. The connection can be made by holding the wire against the piste. A permanent connection can be made by hooking the wire through holes in the exposed corners of the plates. The battery is now re*4y for use.

NOTE: If battery begins to fail after a few firings, scrape the plates and wires where connections are made until metal is shiny.

2. Spread a layer of this mixture, about 1/8 in. (3 mm) thick, on a clean copper or brass (date. The layer must be thick enough to prevent a second plate from touching the copper plate when it is pressed on top.

3. Press an aluminum plate very firmly upon the mixture on the copper plate. Remove completely any of the mixture that squeezes out between the plates. The plates must not touch.

4. If more than one cell Is desired:

a. Place one cell on top of the other so that unlike metal plates are touching.
