Hula hoop - Wikipedia
A
hula hoop is a
toy hoop that is twirled around the waist, limbs or neck.
The modern hula hoop was invented in 1958 by Arthur K. "Spud" Melin and
Richard Knerr, but children and adults around the world have played with hoops, twirling, rolling and
throwing them
throughout history. Hula hoops for children generally measure approximately 70 centimetres (28 in) in diameter, and those for adults around a metre (40 in).
