I want to learn Geoff William's version of Earl Nelson's finger ring move from Variations. I know it's on the DVD, "Miracles for Mortals vol. 2". I'm wondering if it's also explained in Geoff William's live Penguin lecture. Does anyone know?

Here, you can contact Geoff Williams about his products, he would know for sure.

Geoff does not discuss any finger ring effects on his Penguin lecture, but he does a great job with some rubber bands, and explains Forklift (IET bands).
(As an aside, I just got some bands and thread from Eddie Raymond, and they're great).

Miky, it can be found in his lecture notes, "No Adult Supervision", which can be ordered as a pdf download or softbound.

That ring vanish is actually Emile Clifton's move that Nelson credits in his book.

And Earl Nelson refers to it as "Clifton's Ring Move" in his book.
