The World's Largest yo-yo resides in the National Yo-Yo Museum in Chico, California. Named "Big Yo," the 256-pound yo-yo is an exact scale replica of a Tom Kuhn "No Jive 3 in 1 Yo-Yo." Fifty inches tall and 31.5 inches wide, the yo-yo is made of California sugar pine, Baltic birch from the former USSR, and hardrock maple. It was first launched in San Francisco on October 13, 1979.
