This thing has five independent balls that roll around inside the organic ring. It reminds me of an alien version of a ball bearing, even though the inside doesn’t roll separately from the outside like a real bearing does. It’s another fun desk toy to play with during a slow meeting or conference call. If you aim compressed air at the balls at just the right angle, you can get them spinning pretty quickly around the ring!
