A prediction is left in full view on the table. Your spectator picks any card, but his chosen card and the prediction don't match. Then, in split second you visually change the prediction card to the card they have chosen right in front of their eyes. And the best part is, everything can be examined.
1. Easy to do
2. Multiple changes
3. 2 min preparation time
People will freak out because it looks like a camera trick in real life! Enjoy!
