Can someone answer questions about mylar holograms?
A couple of days ago I fond a booth in a shopping mall. Someone was selling these power bracelets. He was saying that it contained some kind of metal that created a mylar hologram. The mylar hologram was supposed to create some "frequency" that was in tune with your own and it was supposed to make you stronger and more flexible. The salesperson was unable to answer any of my questions to my satisfaction. What is a "mylar hologram"? What the hell does he mean be "frequency"? Is it electro magnetic or some kind of sound frequency? How does this work? Is there some source I could look at that could show me a double blind test for this mylar stuff? What kind of metal do they actually put in this thing?
