YOYO

NEED

• While the invention of the yoyo was not imperative, it did provide entertainment

• During its development, centuries ago, the yoyo was used as a hunting weapon

ALTERNATIVES

• As a hunting tool, the yoyo was quickly surpassed by other weapons

• As a form of entertainment, the yoyo is now declining in popularity, but it is kept alive by enthusiasts and other weirdos

RESULTING DEVELOPMENTS

• Though there were no technological developments derived from the yoyo, many were implemented through the yoyo, such as ball bearings

PROTOTYPES

• During the time of its invention, the yoyo didn’t have any documented prototypes, but today, there are many high-tech prototypes engineered specifically to maximize or minimize certain aspects of the yoyo’s motion

MANUFACTURING

• This is a yoyo before being assembled

QUALITY CONTROL

• Most groups of yoyos are tested for height, weight, and size to ensure quality

TODAY’S YOYO

• The yoyo is still in use today, but kids are losing interest fast

• Fanatics have kept the toy alive (seriously, these guys are weird, paying $120 for a yoyo, then talking about it on the forums)

DISPOSAL

• Yoyo disposal varies greatly, because though they are made primarily of plastic, they are commonly disposed of by mothers who compulsively clean with no regard for their children’s yoyo collections
