Touchable is a new development in the Moving Ink effect, using a unique material that makes the moving ink touchable.
Imagine the following. Your spectator selects a card. You then put a dot or X onto the card. Ask your spectator to touch the ink to be sure it's actually drawn on the card. After they have touched the dot, the ink dot moves. Once again, you ask them to touch it - even scratch it if they want. The ink mark still moves!
