You are a magician and you are a little hungry!
This is not a problem for you, borrow a ½$ coin to bite it
. Then you clearly show the small coin piece
that was in your mouth and you restore the coin before giving it back to the spectator.
This very visual trick,
is four-star, has an internal system
consequently less breakable than the other systems. You will even change it yourself thanks to the set provided with the coin.Moreover, this trick is impromptu.Easy to do.
Amazing and efficient.
Provided coin piece.
