“You might be surprised to learn that a yo-yo controlled by 1992 World Champion Dale Oliver was actually clocked at a blistering 14,300 revolutions per minute (rpm). Conversely, the Hornet plods along at a slower 2200 rpm. This is the same aircraft engine, however, that catapulted legendary aviator Roscoe Turner to victory in his Hornet-powered Wedell-Turner racer during the 1934 Thompson Trophy Race. During this race, Turner was able to sustain speeds in excess of 290 mph.”

“The world's record for the largest yo-yo is jointly held by J. N. Nichols (Vimto) Ltd. and the engineering students of Stockport College, Stockport, England. This yo-yo was 10 feet 4 inches in diameter and weighed 897 pounds. It entered the world of Yo on August 1, 1993 when it was "thrown" from a 187-foot crane in Wythenshawe, England.”
