Gravity is Optional - Tumbling Rings

This is an interesting illusion where one ring appears to fall to the bottom of a long chain.

You want to use heavy keyrings - the light weight ones do not work as well.

I get mine from from Walmart - 40 for $5, 2022 - just use 30 per chain.

I started out combining the rings in sets of 2 .. like both videos suggest.

I quickly abandoned this and used a simpler method where I looped a single ring thru 3 at a time.

Create a simple chain of 3 rings
Grab the middle ring so that the other 2 hang at the bottom
Place a single ring next to the 2 .. and loop another single ring thru all 3
At this point, you will get the same 1.2.1.1 configuration shown in both videos
Manipulate the rings, as shown in both videos, to get the 1.2.2 configuration
Place an additional single ring next to the 2 on the bottom and loop yet another single ring thru all 3
Repeat this until only 1 ring is left and loop it thru the 2 on the bottom

I found this much easier to do, but perhaps a lot harder to explain.

Good luck.
