One of the most visual bill effects you can ever do.
Imagine -- your spectator signs a card, it is returned to the deck, and the deck is shuffled. You take a $100 bill out of your pocket and magically, you transform the bill into the signed card! The best part is that the spectator can examine this card and keep it as a souvenir!
There are many variations that you can do with NU FLASH -- you can visually transform a bill into a deck, envelope, named card, prediction etc.
This effect works with any currency, and it's very easy to customize.
