The Centrifuge

In water everything can float around. Material with a larger species weight as water sinks, due to gravity, to the bottom. Lighter parts will float on the surface. A centrifuge does the same thing as gravity, but with a much greater force, which makes sinking and floating much faster. The force, called centrifugal force, also does not work downwards but from the middle of the turning direction. In this way oil, water and heavier parts can be separated. They must all be sucked out or scraped in the correct order.
