The present invention is a toy hoop for use by a person. In one embodiment
of the present invention, the toy hoop comprises a hoop member having
first and second end portions and a first channel adapted to receive flow
of a first medium such as water. The toy hoop further comprises an
interconnect member having first and second end portions adapted to
connect the first and second end portions of the hoop member. The
interconnect member comprises a first channel in communication with the
first channel of the hoop member to allow the first medium to flow there
thru. Each of the first and second end portions have an outside surface
and an inside surface. The inside surfaces are downwardly tapered to
provide laminar flow of the first medium thru the first channel of the
hoop member. The toy hoop further comprises a first inlet port in
communication with the first channel to allow the person to adjust the
volume of the first medium and therefore the mass of the hoop member and
the centrifugal force. The toy hoop further comprises a first plug member
adapted to engage with the first inlet port member to seal the first
channel. In use, the person may fill the first channel of the hoop member
with a desired volume of medium to obtain a desired mass and centrifugal
force.
