  1. You pre-write predictions in invisible ink on a blank pad (you’ll have to add some subtle identifying mark so that you can remember which prediction is written on which page).
  2. You ask someone to choose between options (For example A, B, C or D) saying that you have written down a prediction of which one they will choose in your pad.
  3. When they tell you their choice, you turn to the page that has the correct prediction on it and cover it with a cloth that has developing fluid on it.
  4. Then you slowly unveil the prediction to them, rubbing the developing fluid over the page as you do so and, after you show them the prediction, you show that all the other pages in the book are blank.
