“I have always had a weakness for big illusions, especially that of the woman cut in two! I love doing big close-up illusions because the audience really remembers them.”
CRACK is a big illusion for close-up, yes in front of your spectators you will zig-zag a bank note, a €10 note for example!
Take a banknote, fold it in half lengthwise. Then show the 2 small plates and slide the note between them. The note remains clearly visible since the plates have holes. ZIG-ZAG the bill now in front of your spectators!
