Leap is a Coin-Through-Glass (or Ring-Through-Glass) effect, greatly improved in its presentation and method versus “the old days.”
There have been many great methods available in different formats, such as a pedestal under a shot glass inside of a larger glass, an item resembling a coaster, to utilizing a table.
Some of those items are inconvenient to bring along and use for close-up magic or table hopping.
Leap, therefore, was developed for this effect – it is much easier to use, more convenient to bring along, and doesn’t look suspicious.
And it utilizes something that most magicians already carry with them — a deck of cards!
