Demonstrator consists of a plastic bottle filled with vegetable oil (about the same viscosity as hot engine oil) and metallic particles. Remove the FilterMag, shake the bottle to mix the particles with the oil, and place the FilterMag on the bottle. Watch how quickly the FilterMag attracts and holds the particles against the inside wall of the bottle. Shake the bottle more and the oil will become even cleaner. The FilterMag that comes with the demonstrator is not for vehicle use.
