Abstract
A liquid dispenser that dispenses liquid via the action of a collapsing tube. The illustrative dispenser includes a liquid-carrying tube, a wire, and a magnet. The magnet is shaped to receive the tube and the wire between an elongated North pole and an elongated South pole. A pulse of current of controlled amperage and duration is sent through the wire, which causes it to deflect. This causes the tube to collapse with the result that a portion of the liquid that is contained in the tube is ejected.
