My personal favourites included making an army tank disappear and spending a week in a block of ice, as well as some more simple ones like making a coloured scarf disappear and things like that. The Masked Magician never speaks and never shows his face, to "protect his identity" and he uses different assistants every now and then so we can't figure out who he is by looking at them.
This is one of the few TV shows I ever actually watch. I used to be really interested in magic and like I said it's fun finding out how the tricks are done.
All in all, Magic's Biggest Secrets Finally Revealed is a great TV series for the whole family to enjoy.
