Color:Ultraviolet Purple Infinite rings kinetic spring toy. Fun for everyone. This exciting toy pops up from flat. Flows up and down your arm and can be passed to someone else's arm too! Tactile and visual delight. Feels really cool on your skin as it flows and energizes. Also runs down a thick string or hose. This is a fun way for kids to learn about springs, physics, energy and more. Made of a single strand of high tensile steel. Sharp edges, please be careful.

I love these things
I love these things. They are VERY fun, and make GREAT presents for kids' birthdays! The green was really pretty, and not a color I see these rings in, often

Model of torus flux particle with zero point
I don't know who invented this, but they deserve a Nobel prize.
