Forget what you think you know about the Color Vision Box.
Mental Block by Dan Harlan reimagines a classic of remote viewing with a powerful routine, stunning upgrades, and a beautiful wooden design you’ll be proud to perform.
You introduce a small wooden box and a matching block—both openly examined. A spectator places the block inside the box and simply remembers which color is facing up.
Without hesitation, you name it.
Then comes the surprise.
The block vanishes completely.
And just when the audience thinks it’s over, you raise the stakes again—divining the identity of any object they choose to place inside the box. What begins as a simple test of perception becomes a layered, multiphase miracle.
The Color Vision Box has long been a favorite because it’s easy to perform and devastatingly deceptive. Dan Harlan elevates it with a presentation rooted in the senses, clever refinements, and strong kicker endings that turn a classic into a true closer.
The specially designed block allows for revelations of color, number, letter, shape, and objects, giving you incredible flexibility. The handcrafted wooden finish makes it as striking on display as it is in performance.
Practical. Elegant. Powerful.
Mental Block isn’t just an update—it’s a modern classic built to work, built to last, and built to astonish.
