A magician asks for a volunteer in the audience or uses his assistant to place him or her in a regular cabinet. He then closes the cabinet, waves his wand to tap the box, opens it to reveal that the person is gone! It is believed that there is a trap door or a hidden exit in the box to make it all an illusion.
A Running Gag in this trope is that the person either escapes or doesn't know how to get back in, leaving the magician flabbergasted and the audience booing. For a more dramatic twist, instead of the volunteer reappearing alive and well, the magician opens the box and a corpse falls out. Sometimes a curtain will be used instead if the subject is bigger.
Since it is a Discredited Trope and easy to perform, the ones that often do this magic trick in media are children. A magician will have to really make it presentable and impossible in order to wow the audience.
Compare Smoke Out, a more combat-oriented variant.

- In the Columbo episode "Now You See Him," the water tank escape act that the Great Santini uses to establish his alibi when he shoots Jesse Jerome has got some traces of this. What the audience sees: He scrunches himself up into a water crate that is then sealed shut and tightly secured with chains and padlocks. The crate is hoisted up into the air, and dumped into a water tank at the rear of the stage. After a few minutes go by, the crate is returned to the front of the stage, and is opened, to reveal Santini's daughter, while Santini reveals himself to be one of the black-suited and masked assistants on stage performing during the intermission. What really happens: the wooden crate has a false bottom, and is positioned over a trapdoor when it is on the stage floor. Santini hides in a break room underneath and changes outfits while the crate is in the tank, then sneaks back up to the stage. It is a 15-minute waiting period, so he uses the crate as an opportunity to pose as a waiter to get to Jerome's office and shoot him.

Mainly because it shows how much skill it takes to actually pull it off.)
