ABSTRACT:
A plug and light stick allow a light bulb to be positioned within a common elastic expandable inflatable balloon having an elastic filler neck. The plug fits into the neck of a balloon and seals against the neck wall. The plug has a central bore having an interior end located within the balloon neck and an outer end. The light stick includes an elongated cylindrical tube having a light bulb on the insertion end. The bore contains therein at least one concentric constriction ring and the tube has an outside diameter such that the tube forms a sliding air-tight seal with the constriction ring when inserted in the bore. A pair of electric conductors extend from the bulb, pass along the interior of the tube external the balloon, and connect to an electrical energy source for lighting the balloon. The method involves inserting the plug into the elastic filler neck of the balloon, inflating the balloon by injecting gas through the bore, sealing off the neck interior to the plug, inserting the bulb end, including bulb 35, of the light stick into the exterior end of the plug bore, and positioning the bulb within the balloon as desired.
