Chris Allen, a professional yo-yoist, made an enormous yo-yo out of two dog pools. It's 35 inches across, 18 inches wide, and weighs 5.4 pounds.
This project was in development for two months. For 2 weeks Allen drew up the plans and found the materials, in August Gunter (Splugen on YoYoSkills.com) he found time to build it. Then, for 6 weeks he looked for the perfect location to film the throw. And what better location than on the roof of the National Yo-Yo Museum's parking garage in Chico, Calif.
