WATCH: World record smallest 7x7x7 Rubik's Cube

Puzzle enthusiast Tony Fisher demonstrates a new 3.4 cm-wide cube designed by Matt Bahner. It's half the size width of the original 7x7x7 V-Cube.

Shown above with the original 7x7x7 V-Cube and an original Rubik's Cube for scale, the puzzle retains the V-Cube's curved lines and ships without stickers. Fisher recommends Olivér's Stickers. Though the movement is a little rough because it's right out of the box, it's an impressive engineering feat nonetheless.
