Split Holeis a novelty visual effect created by Chiam Yu Sheng from Singapore. A spectator selects a card and signs their name on it. A hole then appears on the card. The hole splits into two halves, and the two half-holes are restored. Finally, the hole vanishes, and the magician can give the signed card to the spectator as a souvenir. Advantages: Highly visual and practical, perfect for performing in front of live audiences. Super easy to do. The gimmick card is durable.
