Pierced is shock magic at it's finest. Here's the effect:
A stick pin is displayed. The pin is about 2 inches long and is a common type of pin used in sewing. You offer to demonstrate the newest trend in piercings, as you position the tip of the pin against your hand.
The pin is then clearly and fairly pushed directly into the back of your hand. Your spectator can see the pin going deeper and deeper into the flesh.
You ask the spectator if they can see the pin exit the other side and they respond with a bewildered, "Yes!"
They see that the pin has completely penetrated the hand from the back to the front!
