Actually I do know some of his tricks or at l;east the basis of some of them. The throwing of fire from the finger tips is an old majic trick. See your local majic store. There is also several other ways to start a fire with a single drop of water. Of course you need something to burn. There are a number of chemical compouunds that ignite and burn violently when they come into contact with water.
The candy bar and t-shirt one is the old a coke can and a hershey bar.

I suspect most of the so called secrets are things of this nature. Often many of them would require either large amounts or dangerous equipment. Most tasks using simple well known techniques would be easier to preform, More reliable and require less equipment or preperations that these secrets.
No real secrets just a bunch of hype. Although there might be one or two ideas or new uses you never thought of.
