First off, you must obtain: [1] A heat source (hot plate, stove, etc.) [2] A hydrometer, or battery hydrometer [3] A large Pyrex, or enameled steel container (to weigh chemicals) [4] [REDACTED] (sold as a [REDACTED] substitute at health and nutrition stores) Take one gallon of [REDACTED], place it in the container, and begin heating it. While this solution heats, weigh out 63 grams of [REDACTED] and add this to the [REDACTED] being heated. Constantly check the solution being heated with the hydrometer, and boil until you get a reading of 1.3. If using a battery hydrometer, boil until you read a FULL charge. Take the solution and allow it to cool in a refrigerator until it is between room temperature and 0 degrees Celcius. Filter out the crystals that have formed and save them. Boil this solution again and cool as before. Filter and save the crystals. Take the crystals that have been saved, and mix them with distilled water in the following proportions: 56 grams per 100 milliliters distilled water. Heat this solution until it boils and allow to cool. Filter the solution and save the crystals that form upon cooling. This process of purification is called "fractional crystalization". These crystals should be relatively pure [REDACTED]. Powder these to the consistency of face powder, and heat gently to drive off all moisture. Now, melt five parts [REDACTED] with five parts [REDACTED]. Dissolve this in [REDACTED] ([REDACTED]), and pour this liquid on 90 parts [REDACTED] (the powdered crystals from above) into a plastic bowl. Knead this liquid into the [REDACTED] until intimately mixed. Allow all [REDACTED] to evaporate. Finally, place this explosive into a cool, dry place. Avoid friction, [REDACTED], [REDACTED], and [REDACTED] compounds.
