Cause the writing on the back of a playing card to change VISUALLY. The commercial appeal of changing handwriting on a card (not just the card itself) is unusual and unexpected, and with Predichange it's now possible to learn it in minutes!

Here's just one possible effect with the handmade Predichange:

The magician attempts to predict a selected card by writing it on the back of a playing card. Unfortunately, he predicts the wrong card. But then, without EVER moving the card out of view, he causes the prediction to CHANGE VISUALLY into the correct, handwritten prediction.

The special card included (always red Bicycle cards) makes adding this to your repertoire a breeze. The angles are great, and the change is completely automatic.
