A Yo-Yo is basically
composed of two thin round
shaped disks with an axle
connecting at their centers.
A string, usually about 30",
is then loosely attached to
the axle between the disks
and wound up. The other end
of the string is looped
around a finger. The Yo-Yo
is then released from a hand
with a force to propel the
Yo-Yo away from the hand.
The Yo-Yo is only returned
to its starting position if
a small tug is given on the
string. Numerous tricks can
be done with a Yo-Yo such
as: “Rock the Baby”, “Around
the World”, and “Walk the
Dog” to name a few. Most
have heard of the famous
Duncan Yo-Yo brand and
many may assume that
Duncan actually invented
it. Too much surprise, the
Yo-Yo was actually
developed way before
Duncan’s time. He merely
purchased the rights,
trademarked the coined
name, “Yo-Yo”, and made it
widely popular in the
United States.
