The Rubik’s Cube just got a whole lot bigger and harder to solve, thanks to engineering students at the University of Michigan.

An enormous, 1,500-pound Rubik’s Cube sculpture, made of mostly aluminum, was unveiled April 13 on the university campus. The project had been in the works for several years, and was the result of planning and designing by seven current and former mechanical engineering students.

Although it’s not the world’s largest Rubik’s Cube puzzle (that would be this one), it’s definitely the biggest that can be solved by hand.

The giant cube is open to anyone that would like to give it a try, though you might need to wait in line for a while – the builders estimate that it takes at least an hour to solve!

Liberty Science Center’s traveling exhibition, Beyond Rubik’s Cube, is currently on an international tour. It opens in Hangzhou, China on April 19 at Star Avenue and will be there through June 19. Stop by if you’re in the area!
