Imagine a marking system so powerful that a ten-year-old can use it on national television and capture the hearts of many. Now imagine a marking system so obvious that it reveals your words, images, and numbers from across the room, yet so deceptive that it hides in plain sight. Now combine that marking system with one of the most popular children’s building block sets in history, and you have an innovative card game that enables astonishingly direct mind reading. Designed by the DaVinci of modern marking systems, Phill Smith, and refined by one of the hardest-working professionals in close-up magic, Craig Petty, this is a mind-reading tool that audiences of all ages will love. This is MindBlox
by Craig Petty.
Here’s what happens:
The magician introduces a set of challenge cards that block-building enthusiasts can use to test each other’s knowledge and building skills. One card is set aside in an envelope as a prediction. Now the magician demonstrates the difference between mind reading and predicting the future. Additional cards are selected, and the magician can reveal not only which card was selected but also additional information such as the words on the card descriptions and even the total number of bricks in each set. A final card is selected and cannot possibly match the prediction card that was set aside from the beginning.
MindBlox features an incredible marking system that hides in plain sight. The backs of these cards conceal an incredible secret designed by Phill Smith so that every square inch of the card feeds information to the performer while cleverly remaining hidden from your audience. Craig offers ten routines you can perform right away. These cards are so powerful that Ryland Petty used them when he performed on America’s Got Talent, and the recognizable themes and colorful designs will not only delight your audience but also capture their imagination. Read minds, predict the future, and build a reputation with MindBlox by Craig Petty.
