We’ve all heard of the magician escaping from a coffin trick. This is just like that, except for coins. Your friends will be stunned when they watch you make a coin they marked get trapped in a box in your pocket in a matter of seconds. They will be so amazed they may just begin to call you Houdini. HISTORY This is another classic trick from Adams in the 1940s that has stood the test of time with magicians young and old.
