I saw this at this year's Kidabra, when Greg Britt brought a few with him from New Zealand. They sold out in a matter of minutes! A great trick, and now we have them!
Plainly show a mixed up Rubik's Cube to the audience, then put it in an empty box.
Magic, magic, magic.
The Rubik's Cube is taken from the box the cube is now solved!
Each side of the cube has a solid color and you can show all of its sides to the audience.
For the finale, you put the cube in the box again and, when you take it out for the last time, the cube has changed to a solid yellow cube!
Can be shown before and after each change!
Easy to perform! Beautifully made. $125
