Decorative illuminated balloons

摘要

An inflatable translucent balloon body has a predetermined net lifting force upon inflation with a lighter than air gas. A light source is attached to the balloon upon inflation by a light transmitting tether. To keep the buoyant balloon afloat while attached to the light transmitting tether, the light transmitting tether has a net weight of less than the net lifting force of the balloon in an inflated state with lighter than air gas therein.
