I tested Uri myself under laboratory-controlled conditions and saw with my own eyes the bending of a key which was not touched by Geller at any time. There was a group of people present during the experiment who all witnessed the key bending in eleven seconds to an angle of thirty degrees. Afterwards we tested the key in a scientific laboratory using devices such as electron microscopes and X-rays and found that there was no chemical, manual or mechanical forces involved in the bending of the key.
