A phaser is a type of directed-energy weapon used in science fiction, typically in the form of a hand-held device. A taser is an electroshock weapon that uses electrical current to disrupt voluntary control of muscles, causing 'neuromuscular incapacitation'. An airtaser is a type of taser that uses compressed air to fire two small dart-like electrodes, which stay connected to the main unit by conductive wire as they are propelled by small compressed nitrogen charges.
