I had a discussion with someone on the Internet that my communications were untrue. There was page after page of writing until I eventually said:- "Okay...I will ask them to show themselves in front of my camera" So I took my camera to my garage at Wollaton. Set it to 0 flux as I stood in front of it... Holding out the palm of my left hand and pointing to my palm with my other hand. This was not enough, so I said I would do it again and precisely the same thing happened. The film is a good twenty minutes but here are two snippets. Temperature was minus twenty degrees C. as this was the coldest day for many years.
