C3yoyodesign - Plasma Crash A variant of the Hydrogen Crash. Slightly smaller and with even more sleep. This is a variant based on the Hydrogen Crash. It is a slightly heavier, with a new rim weight balance. While the Hydrogen Crash was lighter and had a sharp feel, the Plasma Crash has a more responsive feel and more sleeping power, while maintaining that sharpness. The difference may seem slight when just comparing the two, but the more you use the yo-yo, the more obvious the difference becomes, and the more you want to try new tricks that are possible with this power, the more reliable the yo-yo becomes. Another key point is that the yo-yo is slightly smaller while maintaining its wide size. The difference in diameter is only a little less than 2mm, but this makes it harder to hit your fingers and also makes it easier to change direction, differentiating it from the Hydrogen Crash and at the same time giving the Plasma Crash its unique character.
