Sponsors and Curators The Museum of Yo-Yo History is a labor of love, and we would not be able to stay up-to-date with exhibits without the support of our sponsors and curators. Big thanks go to One Drop Design and Duncan for supplying us with their latest models, YoYoExpert for their help and support, and to Cody Orr, TotalArtist and YoYoBrothers™ for allowing us to use their collections! If you're a manufacturer, or just a big collector and you want to help support the Museum drop me at line at chimera@yoyomuseum.com Yomega X-Brain Yo Dawg - #2 of 6 Exhibit #2111 Type Special Release Shape Modified Axle Transaxle - Plastic Color Blue Packaging Boxed Construction Multi-piece plastic Response Starburst Gap Fixed Condition Mint in Package Date 2000 Owner Rick Brough Compare An X-Brain yo-yo. Number two of six Yomega yo-yos offered by McDonald's between November 21 and December 21, 2000. The "X-BRAIN" yo-yo is a plastic yo-yo with a centrifugal clutch, and it works this way: when the yo-yo is thrown hard enough towards the ground, the clutches separate and allow the yo-yo to spin freely. As the yo-yo slows down, springs push the clutches back together until they grab hold of the axle. At this point, the yo-yo winds up and returns automatically to the player's hand. "With the purchase of any Yomega/McDonald's X-Brain or Firestorm for $2 (food purchase necessary), you could be the proud new owner of a Power Brain. Inside every package looms the chance of winning this new generation of yo-yo." Original retail price: $4 US. Other Views Package front, angled Package back Complete set 2005-2023 Software © David W.
