“You’ve got the signed coin, and it’s in THIS hand!” You’ll be able to say this!
If you have ever wanted to perform a ‘coin in which hand’ type of effect, Gerti Reborn is for you. You have two coins; you ask a spectator to sign one of the coins. You invite the spectator to place one coin in your hand and to place the other coin in one of their own hands. Without looking, not only are you able to reveal which of you has the signed coin, with the updated Gerti Reborn you are now able to tell the spectator which coin they have, as well as in which hand they hold the coin.
