Cristal

The best place to hide a secret? In plain sight.

There's a challenge with prediction effects: the more impossible the revelation, the more your audience suspects you've secretly switched or loaded something.

But what if the very tool you used to reveal your prediction could also be hiding the secret? And what if that tool were completely transparent?

"Cristal," is an ingenious billet knife from Gonzalo Albiñana and Crazy Jokers that lets you secretly load predictions while appearing to do nothing more than open an envelope.

Here's what your audience sees.

You display an envelope and a crystal-clear letter opener.

With everything in full view, you slice open the envelope and pour out a folded piece of paper.

A participant unfolds it to discover an impossible prediction.

No suspicious switches. No awkward cover-ups. Just a remarkably clean revelation.

What is "Cristal"?

Crafted from high-transparency photosensitive resin, "Cristal" looks like a piece of clear glass. But concealed within its elegant design is a powerful loading system.

As you naturally open an envelope, you secretly introduce your prediction.

And you're not limited to tiny billets. "Cristal" can load up to a folded A4-sized sheet of paper, making it equally useful for intimate close-up performances and large theatrical productions.

More than just envelopes!

"Cristal" can also be incorporated into routines involving fruit, balloons, and packages, giving you plenty of opportunities to disguise the secret action within an ordinary task.

The included video tutorial features Gonzalo Albiñana explaining the handling, creative possibilities, routine variations, and practical applications.
