The Clear Principle by Pham Huy and Danny Goldsmith

This might not be the first time you've seen Coin Through Glass. But it's definitely the version you'll actually use. The Clear Principle: A simple principle that removes every major limitation of one of close-up magic's favorite plots. A truly impromptu, gimmickless, easy to perform coin through glass, for any occasion. Adaptable to rings, keys, bottle caps, and almost any other small object you have on hand. Coin through glass is a classic. It's a plot magicians have loved and chased for years, and for very good reason: nothing beats watching a solid object pass through solid glass, right in front of you. But every version currently out there comes with a catch. They're not impromptu. They need elaborate setup. Or expensive gimmicks. Or finger-busting, expert-level sleight of hand skills. Or the mouth of the glass is left wide open, making the penetration less convincing. Or they only work with one very specific coin, bottle, or glass. The Clear Principle removes every one of those problems... ” The Clear Principle is a refreshing take on the coin/object through glass. It’s probably the closest version you can get compared to any gimmick version. Great job! — Henry Harrius
