KINETIC FLOW RING
KINETIC FLOW RING
The Kinetic Flow Rings are constructed from a single continuous strand of steel which coils up flat and pops open into a sphere. It spins whilst falling and with momentum it will even go up. You can put your arm through the coils and it will roll up and down your arm and you can even pass it to your friends by holding hands. It will also work on tubes of cardboard or a rope.
The science behind it is the way the steel coils through itself forming a Torus Knot. It is a bit like a 3D slinky, but unlike the slinkys which seem to have the ability to tangle, the kinetic rings seem to be quite robust and tangle-free. Hours of fun can be had with this...
