Project Alpha: Randi Exposes Researchers

Stage magician James Randi exposed paranormal researchers in a four-year sting operation called "Project Alpha," where two teenage magicians infiltrated the McDonnell Laboratory for Psychical Research using sleight-of-hand tricks. Despite dropping hints and suggesting foolproof experiments to the researchers, they initially refused but eventually conducted the experiments, leading to the exposure of the deception. The revelation by Randi publicly humiliated the researchers, leading to the shutdown of McDonnell Laboratory after a few years.
