Split Rings for Magician's Chain

A Magician's Chain is usually made from metal split rings but I wanted a coloured version. The individual rings are 30 mm in diameter, with a 2 degree gap in the circumference so that the rings can be slotted together.

I did not polish the rings as this was not necessary for the chain to work.

The video shows the chain doing its magic.
