Faraday entered a big metallic cage supported on insulating pillars and then charged the cage by a powerful electric machine. He remains quite safe inside the cage. Do you believe on this happening?

Charges reside only on the surface of a conductor. Inside the conductor, charge is zero. So even, if the metallic cage was charged up with the help of powerful electric machine the charges resided on the surface. Therefore, we believe that Faraday was quite safe inside the cage.
