Biting a coin in half
If you would like to perform this trick yourself, then whatever you will have to do is buy a fake coin designed to look like an authentic one, however it breaks when placed under pressure.
Then you will have to practice your sleight of hand since you need to change the coin you obtain from a volunteer to make certain you don’t inadvertently break your teeth while attempting to munch a true coin. The trick to doing this trick nicely is the sleight of hand, something street magicians are experts at.
