Any Base Metal in a Rail, Bucket, or Shears recipe will produce a basic version of said item. For Rails you get more/less rails based on the metal used. Also any Precious Metal can be used to make Booster Tracks, resulting in more/less of said track based on the metal used. Sep 26, 2015 You can add custom music to your support chopper. In this case, songs from 1993. Edit 1: Thanks everyone for your kind words:) Edit 2: If you're interested, here is my Mortal Kombat spin-off.

Electricity is the flow of tiny particles called electrons through a conductor.
Sizes of particles as dust, pollen bacteria, virus and many more
The size of contaminants and particles are usually described in microns, a metric unit of measure where
- one micron is one-millionth of a metre
- 1 micron = 10-6 m
In imperial units
- 1 inch = 25400 microns
- 1 micron = 1 / 25400 inch

Airborne particles
Airborne particles are solids suspended in the air.
Larger particles - larger then 100 μm
- terminal velocities > 0.5 m/s
- fall out quickly
- includes hail, snow, insect debris, room dust, soot aggregates, coarse sand, gravel, and sea spray
Medium-size particles - in the range 1 to 100 μm
- sedimentation velocities greater than 0.2 m/s
- settles out slowly
- includes fine ice crystals, pollen, hair, large bacteria, windblown dust, fly ash, coal dust, silt, fine sand, and small dust
Tiny Metal Multiplayer
Small particles - less than 1 μm
- falls slowly, take days to years to settle out of a quiet atmosphere. In a turbulent atmosphere they may never settle out
- can be washed out by water or rain
- includes viruses, small bacteria, metallurgical fumes, soot, oil smoke, tobacco smoke, clay, and fumes

Hazardous Dust Particles
Smaller dust particles can be hazardous for humans. In many jurisdictions dust fractions at specified particle sizes in working environments are required to be measured.
Inhalable Dust
Airborne particles which can enter the nose and mouth during normal breathing. Particles of 100 microns diameter or less.
Thoracic Dust
Particles that will pass through the nose and throat, reaching the lungs. Particles of 10 microns diameter and less. Referred to as PM10 in the USA.
Respirable Dust
Tiny Metal 1.0.7 Windows
Particles that will penetrate into the gas exchange region of the lungs. A hazardous particulate size less than 5 microns. Particle sizes of 2.5 micron (PM2.5) are often used in USA.
The total allowable particle concentration - building materials, combustion products, mineral fibers and synthetic fibers (particles less than 10 μm) - specified by EPA (U.S. Environmental Protection Agency)
- 50 μg/m3 (0.000022 grain/ft3) - allowable exposure per day over the course of 1 year
- 150 μg/m3 (0.000022 grain/ft3) - allowable exposure over 24 hours
