A group of students at the University of Michigan have created an enormous, fully-solvable Rubik's cube that can turned by hand.
The massive contraption will sit in the university's campus and – while it's definitely not the largest Rubik's out there – it's the most sizeable "human manipulable cube" in the world according to the university.
"The point of making a Rubik's cube so large was primarily to introduce teamwork to the puzzle-solving process," says Michigan graduate Martin Harris.
The cube weighs 680kg and is primarily made out of aluminium. That's all to say that if this "toy" fell on you, it would hurt – a lot.
"The colorful, new cube is meant to be touched and solved," says Michigan Engineering. "The students worked hard to figure out a movement mechanism that would enable that.
"They realized they couldn't simply scale up the approach a handheld cube relies on because the friction would be too great. So to keep friction minimal, they devised a setup that utilizes rollers and transfer bearings."
A group of seniors at the university initially began the project, but ran into a problem which made it impossible to turn the faces. Responsibility for the cube was then passed down to a group in the year below, who implemented a solution and finalised construction.
The world's largest Rubik's cube, as verified by Guinness World Records, is 1.57 metres cubed but has to be rolled over and turned by hand.
