Bullet by Matt Mello
Introduce speed to your coin in bottle.
Matthew Mello and Nick V. created Bullet. A plastic bottle is shown unmistakeably empty, then a borrowed coin is SIGNED (if desired).
The coin is slapped against the bottom of the bottle and flys into the bottle like a... bullet.
It is possible to borrow the bottle, the coin, and perform a signed version of Bullet. All of this is taught in detail by acclaimed master Justin Miller.
