Full Overview
A borrowed quarter held at your fingertips is visibly punctured with a pen-- leaving the quarter shish-ka-bobbed onto the pen!
The permanently punctured quarter and pen are immediately handed out for examination. There's only one explanation... you've somehow discovered how to really poke a pen through a solid coin!
The visual illusion of the pen going through their own quarter is 100% "oh my god" perfect. The actual borrowed quarter is in full view as the pen contacts the coin.
The pen is normal and fully examinable. Complete with pen, gimmick, and instructional DVD. This effect was considered and filmed by David Blaine for the David Blaine: Drowned Alive Special.
