Way, way off topic.

A tube formed from spiral weaved leather. Push a finger into either end of the tube and then pull, and no matter how hard you pull, you cannot pull your fingers free. Indeed, the harder you pull, the tighter it grips.

A "magic trick" or just a curiosity. But what is it called?

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority".

In the absence of evidence, opinion is indistinguishable from prejudice.

I will unfortunately always remember those as "finger cuffs" because of the Kevin Smith film "Chasing Amy". -- John.	[reply]
