The Torofluxus was invented in the early 1990s by a craftsman in Germany. A 28ft long ribbon of fine flat spring steel is woven into a torus and the ends spot welded. It comes attached to a plastic core, and when released the spring opens up into a torus shape. If you then pass the core through your hands, the torus flows downwards gripping onto the core and shimmering like a silver bubble.
It is quite hard to describe, but it always gets 'ooohs' and 'aaahs' when we demonstrate it.
