Look: If we’re being honest, fidget spinners are pretty played out at this point. Or at least they are ... on Earth. It turns out that fidget spinners remain extremely cool if you have access to a massive spacecraft and a low-gravity environment.
NASA astronaut Randy Bresnik, who is stationed on the International Space Station, recently took some time to demonstrate that you can just set one of these bad boys going in Earth orbit and it will just pretty much just go on forever. Because there’s less friction between the spinner’s components, the whole toy rotates in sync, not just the arms.
“Allowing the fidget spinner to float reduces the bearing friction by permitting the rate of the central ring and outer spinner to equalize, and the whole thing spins as a unit,” Bresnik explained in the video caption.
Per GeekWire, some of Bresnik’s colleagues including Mark T. Vande Hei, Joseph M. Acaba and European Space Agency astronaut Paolo Nespoli all make appearances in the clip. Behold:
