Banked by Taiwan Ben
Banked is an amazing improvement to the Coin Through Bottle effect. You borrow a coin from a spectator, then visibly and instantly slap it through the bottom of ANY plastic bottle. This new version of the effect does not require any glass or "special" bottles or any unnatural handling, and is completely examinable before and after the effect. You can finish your drink (or borrow their empty bottle), borrow a coin, and create INSTANT magic!
Comes with detailed instructions, as well as something special that turns this effect into an almost effortless miracle!
