Abstract
A propulsion system for an appliable product, includes a distal tube which has an open end. A proximal tube is rotatably connected to the distal tube on a common central axis to form a cavity. A holder which carries the appliable product is shaped and dimensioned to slide in the cavity along the common central axis. A line having two strands connects the distal tube and the proximal tube. When the proximal tube is rotated with respect to the distal tube, the two strands of the line twist together and the line exerts a force upon the holder so that the holder moves toward the open end of the distal tube.
