Do you want to know how to chain a ring which is falling down when you release it? Now you can impress your friends! Really amazing and easy trick.
Because of my low skills in English, I did a mistake in the vid. You must read "thumb" instead of "inch" word. And if you do not understand, read it:
In fact, you must hold the ring between your index and middle finger (and the thumb on the other side). Your two fingers must be parallels to the chain. You can see the pic which is zooming in the video. And after you must release the ring with your thumb in first. It will rotate and roll on the chain to make a node. That's all!
