Blank Inside by Kyle Purnell

You begin by asking the spectator to name a number - twenty-five for example. That number becomes your time limit as you frantically begin cutting the deck and removing cards, one at a time, within twenty-five seconds.

With just a second to spare, you drop the deck to the table, announcing that you’re done. But then you realise that you never actually explained what your aim was.

The named number - twenty-five - was, in fact, your target. Turning over the cards one at a time, you reveal that they add up to twenty-five. But that’s not it...

You then explain that the trick actually only works with one number. Twenty-five.

As you turn over the rest of the deck, you’ll get gasps as you show that every single card is blank! It’s a stunning ending that will baffle even the most discerning audience members!
