So much fun, you can't put it down! Almost like a futuristic-4th dimensional / magical "Sliinky." A mesmerizing kinetic sculpture that folds flat and pops open, surprising everyone. Comes with a carrying bag, so you can bring it everywhere to share and spread the fun :) Diameter ~5" when flat. Exact size may vary. Put your hands through it and run it safely along your arms (bare arms work best) and pass them from arm to another, or one person to another just for fun or in a dance. Running it along a flexible tube (e.g. an extension cord) makes it look like a metallic soap bubble and is an intriguing way to observe interlocking strands of metal in motion. You'll become instantly addicted to Toroflux!
