Cosmonaut | Mental Omega Wiki | Fandom
Cosmonauts are special infantrymen trained to fight in the hard vacuum of space. Cosmonauts are equipped with all the necessary life support equipment to survive in the vacuum and a jet pack like that used by Allied Rocketeers. They are armed with a laser cannon that is most effective against enemy infantry and vehicles. In Earthrise, Cosmonauts serve as the main infantry unit …

Ball Mill vs Coffee Grinder - Pyrotechnics - Forum
Page 1 of 2 - Ball Mill vs Coffee Grinder - posted in Pyrotechnics: instead of ball milling, can I just use a number of different coffee grinders to separately grind each chemical to a very fine dust, before I mix them by either the diaper method or mesh screens. Those little blade coffee grinders work really well for Potasium Nitrate and Sulfur.

The chemistry behind fireworks | Penn Today
The oxidizer is receiving the electrons; upon reaction with the oxidizer, energy is released, and the electrons are transferred from one to the other. So you're creating a mixture of the fuel and the oxidizer, and that's a lot of stored potential energy that's ready to be released. You just need a spark under that situation to get the ...
