SIGNED?! LOCKED?! IMPOSSIBLE?! Crystal Prison Review

A signed, mixed Rubik's Cube disappears, only to reappear inside a locked, transparent box that the spectator can open themselves.

It sounds almost too clean.

In the latest Magic Pulse Review, we put Crystal Prison by Flat Base & TCC Magic to the test. This one was particularly interesting because I've performed Rubik's Cube magic professionally for years, including hundreds of performances of Cube in Jar, so I had a pretty clear benchmark going in.

Crystal Prison promises something very different: a powerful cube to impossible location with almost no preparation, minimal technical requirements and a reset that makes repeated performances genuinely practical.

But does that convenience come at a cost? How deceptive is it in the real world? And most importantly, is it actually a worker?

I've already performed it for real audiences, and the final Magic Pulse verdict is..... Well. Watch the full review and see why Crystal Prison scored so highly.
