 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

Cajun Spinner's Rotational Kinetic Energy Yeaux-Yeaux first released in a color-shifting blue on June 19, 2023.
From Cajun Spinners:
"The science of physics goes hand-in-hand (pun intended) with yo-yoing. As the yo-yo is thrown down, it rotates around its axle, the energy it generates on the way down is known as rotational kinetic energy. The formula for determining the amount of energy generated is featured on the sticker design applied to both sides of this Cajun Spinner's Yeaux-Yeaux. Enjoy!
The yo-yo in this exhibit features a color-shifting metallic blue, which slightly changes hue when viewed at different angles."
This model came in the following colors:
• Metallic red, color shifting
• Metallic green-copper, color shifting
• Metallic blue, color shifting (seen in this exhibit)
Rotational kinetic energy
The equation printed on the sticker is the equation for kinetic energy of a rotating object, where:
• Ι = Moment of inertia (a measure of how mass is distributed relative to the axis of rotation).
• ω = Angular velocity (how fast the object is spinning; in this case, the yo-yo).
• Ιω² = The rotational kinetic energy formula.
While "Erotational" is not a standard physics term, it was likely used as a creative way to emphasize "rotational energy" in a playful way by John Myshrall, owner of Cajun Spinner's. This second version of the yo-yo fixed the first version that was released with a small error in the equation printed on the sticker seal.
