The Physics Behind Four Amazing Demonstrations

Willey, interested in psychics and wanted to get people's attention. In order to do that he had to spread the word on the importance of psychics in a dramatic way. Walking on a broken glass technique purpose of his demonstration is that what we may perceive to be true may be wrong. Like walking on glass ask any normal person they would say, "no way". However the best way to perceive this is the fact that in order to do anything you must take acknowledgement that it can happen. There are ways to go around things that seem dangerous and scary at the time.His next experience was dipping his fingers in molted led, and bed of naild and breaking a bed of blocks. He is a very unusual man with a high education level my question is what is the purpose of him doing all this crazy stuff? to prove a point on physics what one perceive something is may not be the same once you do it.
