More Slinky Torus Magic

By now you realize that you can make a torus model using a toy Slinky. You pull the two ends together and secure them to each other to make a donut.

Yesterday I was showing a friend how, if you stack two such Slinky tori one upon the other, they fall through one another without interference. Take a look at this short video of me pushing one Slinky through another.

What puzzles me is how neatly the curved tines of the two objects pass through each other without becoming tangled.  Try it yourself! Take any two Slinkys of any size and replicate. Great fun!
