  - inherently dirty
* is loaded by grains of volume

+ Black powder rocket motor, History: Rockets :: Fuel
  * Black powder is the oldest type of mixed rocket fuel. It was used in rockets even before it was used in guns. Before that it was only used for fun. The first recorded use of rockets as military weapons was in 1232. The black powder was packed in a closed tube that had a hole in one end for escaping hot gases. The tube was mounted on a long stick so it was more balanced.
+ Specific impulse, Examples, Model rocketry: Spaceflight :: Mechanics
  * Specific impulse is also used to describe how well model rocket motors work. The specific impulse for model rocket motors is much lower than for many other rocket motors because the black powder is used as a fuel. Black powder is used in model rocket motors because it costs less.

Chili powder

  - made by separating most of the cocoa butter out of the liquor

Garlic powder
* can be used in mashs, it helps prevent infections and parasites
  - help satisfy cravings for salt
* is good to add to discourage fleas.

### powder:

Gun powder
* Take white paper or a white sheet, spread it on the ground.
* is packed into metal cylinders behind the bullet, called the cartridge
  - part of fireworks
+ Gunpowder: Firearms
  * It burns very rapidly, and creates gases. Those gases use up more space than the gunpowder they come from, so they push outward. If the gunpowder is in a small space, the gasses will push on the walls of the space, building up pressure. A bullet  is pushed on in this way inside of a gun, causing it to fly out at high speeds. Gun powder is packed into metal cylinders behind the bullet, called the cartridge.

Iron powder
* demonstrates the distribution of the magnetic field.
* is used as a carrier for toner in electrostatic copying machines.

Loose powder
* has a consistency more like baby powder - soft, fine, and, well, loose.
* is good for the eye area to prep for eye shadow.

Milk powder
* Most milk powder has density
  - different density
* is milk
* poor substitute for mother's milk.
* works great as a food thickener.

Pearl powder
* contains a natural moisturizer.
* keeps the skin clear and smooth, leaving it with a sheer, radiant glow.
* natural moisturizer that revitalizes skin cells.

Protein powder
* are available at most health food stores.
* mixes with water.
* supply much more protein then necessary and the majority of it is converted to fat.
* work in the sense that they make it easier to eat a lot of protein.
