Using your keys, phone and wallet, you can do a cool free will type of effect with Rostami's IForce app.

Have your spectator put the objects in any order he likes, and simply reveal their chosen order as being predicted by you in advance.

That's all, enjoy.

Nice idea. Personally, I like using iForce with Glance (Vanishing Inc). You literally don’t have to do anything to get a direct hit on their selected word, except ask them to say it aloud. Once they do, you turn over the phone to show what you “wrote” down and it is their chosen word. It’s absolutely killer.
