Effect

Sum Duo is a digital magic trick that uses borrowed phones to create a surprising and interactive experience. The magician asks the spectator to enter personal numbers into their phone's calculator, such as a rating, birth month, or even how many pizzas they ate last year. After a series of calculations, the magician reveals the final number without ever touching the phone. The effect is clean, direct, and leaves the spectator amazed at how their own inputs led to a precise prediction.
