A multi-purpose projecting device for propelling and disseminating, generally vertically, paper disks, confetti, or fluid contained in a cartridge. Contents of the cartridge as well as the outside surface of the launching tube may be covered with a fluorescent material. The launching tube may serve as a flagpole to supplement its primary function at large social gatherings such as sporting or music events, wedding ceremonies, holiday celebrations, etc. The device consists of a two-part cylindrical launching apparatus and a cylindrical cartridge that may hold paper disks, confetti, fluid, or other soft materials such as fiber, string, fabric, etc. The upper section of the launching tube folds back, into which the cartridge can then be inserted. The lower section of the launching tube consists of a spring, a plunger, a spring, a string, and a trigger. After the cartridge is loaded, a string connecting to the plunger is pulled, contracting the spring and setting the trigger ready for launching. The upper section of the tube is then restored to its original position. Pressing the trigger releases the plunger, which moves along the launching tube due to pressure from the extending spring. The plunger compresses air within the tube, propelling contents of the cartridge through the upper section of the launching tube to be ejected.
