You introduce a brass key and a coin. You then tell your audience that you will give them 100 euros if they can push the coin through the hole in the key. After the audience tries and realizes it is impossible, the magician offers to show them how it’s done. With just a rub, the hole in the key magically expands tenfold in size, becoming a coin-sized slot. The magician can then easily drop the coin through the key before returning the hole to its normal size. Everything is inspectable.

Gatekeeper is a completely self-contained effect that uses simple sleight of hand to perform this amazing trick. The props are custom-made to Craig’s exact specifications and fit perfectly with the Key Master set, so your routine possibilities are endless. Gatekeeper is ready to use right out of the box.
