Found this video on Facebook now. I thank my old friend, magician Robert Lamar, for this link.
For a long, long time, people have been throwing their money at fake "psychics", people who claim they can communicate with the dead. Yeah, right.
In the 1930's, Dunninger, a magician best known for popularising mentalism, went around debunking these charlatans, much as Houdini had done 20 years earlier.
Here is a short film featuring Dunninger exposing some of these tricks.
Following that, is a short piece on how the early Disney cartoons were made.
Fascinating stuff. I hope you take the time to watch it.
