A borrowed coin is marked and placed on the tongue (or on the fingertips) and penetrates the Lollipop and back.
The coin could be seen inside of the Lollipop from both sides.
The Lollipop is unprepared.
Make the gimmick in 2-3 minutes.
Works with coins, cards, banknotes and other flat items. Included is an impromptu version with a borrowed marked coin and a borrowed Lollipop.
