ABSTRACT:
An aerodynamic, neutrally bouyant, mylar toy, comprises itself of a helium filled, mylar brand balloon with its accompaning convenient, flexible one-way valve, which is specifically weighted at its perimeter to exhibit dynamic flight characteristics due primarily to its centrifugal properties.The aerodynamic toy is weighted with a variety of ballasts to achieve a horizontal, neutral buoyant, list-free, static equilibrium attitude. Such ballasts are ingeniously positioned to first offset the intrinsic weight of said fill valve to create a list-free horizontal attitude. Ballast is subsequently added to the perimeter until said toy is counter-ballanced against the forces of gravity. In the case of a round balloon weighted and positioned horizontally, some ballast is added at its southern most concentric axis in order to easily facilitate the return of a neutral buoyant attitude of said toy, due to the inevitable loss of helium,and without effecting its said static, list-free equilibrium. Means are described to concisely and creatively weight several aerodynamically shaped balloons and it is the specific placement at their perimeters that dramatically enhances the flight, spin and stability of any or all helium filled, neutrally balanced, mylar toys.
