Most tricks have a very short explanation. Something is just a fake prop. A hidden breathing tube in the water. The camera is upside down. The nails are popped up from the table, not shot from the gun. The selected card is forced by sleight of hand. Like a video game or a movie, there's a fake trigger and a fake effect and then there's a mockup of the appearance of the connection between. Making it look good requires a lot of detailed work, like painting a miniature city for a movie, which bores most people, but the trick is explained very simply.
