This is the video referred to above. The spoon she's using is a cheap thin one. Read my comments under that video as "galla1968" and her replies to them. In a later video she gives her explanation in defense of why the spoon already had a slight bend. Note the way she avoids addressing my point though, even when I throw her own words back at her - that the spoon was a "light" one with "a lot of give". Instead she says it was a "normal" spoon to divert attention from the fact that she already admitted it was easy to bend.
Most of us assume a spoon is hard to bend by brute force, and even find we can't do it when we try. But give someone a spoon and a strip of metal of exactly the same weight/thickness and I suspect they'd easily bend the strip but not the spoon - because they subconsciously don't want to destroy the spoon.
However, spoons are easily bent, especially light ones like the one in her video. We've all bent a spoon just by pushing it into hard ice-cream! I twisted a much better quality bevelled dessert spoon into loops after warming it for 2 minutes between my fingers. It really wasn't that difficult. Using her method, where you hold the spoon between your hands for a while and "meditate", you do in fact lose biofeedback, the sense of how hard you're pressing on the spoon - hence, I believe, the reports of the metal "turning to putty". Similarly if you hold a spoon at the neck between finger and thumb for a while, you can no longer feel the spoon, and then when you wiggle the spoon it feels paper-thin.
