Did you ever have a Slinky? Those loose springs which “walk” downstairs. They've been around since the 1940s and, like Jacob's Ladders, they'll likely always be around.
These infinity rings are in the same family of stims as the Slinky with one important difference – you don't need stairs for them! What starts as a short stack of thin metal rings pops up into a big fat springy donut. Cool.

This flow ring fidget toy is made out of thinner metal and could be bent if forced or stretched too much. Not recommended for children younger than four. This stim toy measures about 5.3 inches and is made from aluminum.
