Alcatraz (previously sold as "Resto") is a clever gimmick that allows you to reseal a bottle right before your spectator's eyes.

If you perform "card in bottle" effect, you'll show a bottle with their signed card inside, and with the Alcatraz gimmick, you'll "pretend" to open it. In fact, by pushing down the gimmick (as shown in the photo), you'll reseal the bottle with what looks like a manufacturer's seal. In just a second, the bottle is locked again. This leaves you able to present it as a sealed souvenir, card inside, leaving a lasting impression!
