In Focus by Joel Dickinson & Andrew Dean
In Focus is a card to impossible location and it can be used to switch predictions and make objects appear.
In Focus literally takes up no pocket space, yet creates an interesting moment the second you arrive to perform.
With minimal practice you will be ready to perform a large selection of routines limited only by your imagination.
If you are worried somebody will see a card under your lapel, there's really no need to worry there is NOTHING to see.
