Pouring 4 quarts

A farmer needs to add exactly 4 quarts of weed killer to the fertilizer mix that he s preparing to spread over his field. Unfortunately, he has only a 3-quart container and a 5-quart container, not a 4-quart container. He can t just guess. The accuracy of his measurement is most important. How can he measure exactly 4 quarts with the two containers he has (There are several possible solutions, but the farmer wants the one that takes the fewest number of steps.) 

Answer The farmer fills the 5-quart container and empties 3 quarts from that container into the 3-quart container, leaving 2 quarts in the 5-quart container. Then he empties the 3-quart container and pours the 2 quarts from the 5-quart container into the 3-quart container, leaving room in the 3-quart container for another quart. He fills the 5-quart container again and pours 1 quart into the 3-quart container that already contains 2 quarts. That leaves exactly 4 quarts in the 5-quart container.

A 475-mL volume of fuel and 25 mL of distilled water are placed into a stainless steel, explosion-proof blending vessel. The fuel and water are stirred at low speed (10,000 RPM) for four minutes using an explosion-proof Waring blender. The mixture is then poured into 1-quart square bottles and the fuel layer and water layer are rated for clarity after 1, 3, 5, 8,12 and 24 hours. A rating scale from 0 to 11 has been developed to describe fuel clarity and appearance. 

The galls aro to be boiled with three pints of wator till a quart of decoction remains it is then poured off, the remainder of the water added, and ebullition continued until again a quart only is left.

Let the iodine mixture sit long enough for the sediment to settle and discard as much of the clear liquid as possible before filtering the sediment. Hold the filter cone over a clean, wide-mouthed, 1-quart glass jar and pour the liquid containing the sediment into it. The sediment is your explosive. The small amount you have just made will go much farther than you realize. 

To make, place a 1-pound chunk of commercial pressed-wood fixe log in a microwave and heat for about 3 1/2 minutes (at defrost). Remove and break the chunk apart with a fork. Pour the resulting loose mixture into a 3-pound coffee can and add a 1-pound box of napthalene moth crystals. (If for some reason moth balls must be used, they should be soaked in a little diesel for a week or so, which will dissolve them.) Put the Lid on the can and shake to mix. Pour in diesel fuel until the mixture is well soaked. Do not use too much diesel—about a quart is usually fine, but this may vary. Stir until evenly mixed. Let it sit for a couple of days and stir again. The napthalene should be dissolved. It is now ready to use.

When the contents have cooled, pour them into two quarts of water and treat as you did while filtering the final processed potassium carbonate. You may want to crystalize it as described in Dick s process further on in number 4201 ...
