ABSTRACT:
An airborne, free floating, lift-weight balanced toy for manual manipulation includes a closed envelope of polyethylene terephthalate (Mylar) filled with helium. The envelope is exactly counterbalanced with one or more ballast members so that the toy will assume a position at a desired distance from the floor or ground when it is let free. Such ballast members are made up of a plurality of weight control modules spirally arranged with respect to each other and held onto the skin of the toy by double face adhesive. In one form of the invention, when such a toy is initially filled with helium and a ballast member is in place, it will have a static balance such that one portion will always come back to being the bottom portion. In a second form, two ballast members are placed so that the toy will remain oriented in space in whatever position it is manually placed, if there are no outside effects except gravity and the lifting effect of the helium working on it. In each form, the ballast members are so positioned with respect to the skin of the toy that when one or more weight control modules are removed serially from the outer end of the spiral toward the inner end thereof, this static balance is not appreciably disturbed.
