Gnu,

those tested all claimed they could do it with stagnant water. But I only have introduced that example for their amazing lack of testing themselves. They all were notified in detail how the test would be done and how they could test themselves under the same circumstances to avoid public embarrassment but they still came. I think it should be easy for someone who claims to be able to find stagnant water under a cover if being told that in the test situation he would not know under which cover the water was to do that test at home with his wife or a friend.

s&r, (1) we are some factors ten away from the realm of Schroedinger's cat
(2) he had told me he could do it with all kinds of people watching and some of them he said were initially skeptical
(3) I did not interfere with his 'magic', it worked like it ever did, only it also did work without him. For the cat analogy to be working you must postulate that I (being skeptical) did make the other cloud disappear to get the result I had wished. That's the Conan Doyle argument that nobody is taking serious.
