You probably don’t recognise the name Que Jianyu, but you may recognise his work.

Any time a ridiculous Rubik’s cube feat has been completed, there’s a good chance it was this Chinese teenager who did it.

Earlier this month, on Guinness World Records (GWR) Day, he set records in the some incredibly specific categories, including one he created.

The 13-year-old set the fastest time to solve three Rubik’s cubes simultaneously with both hands and feet – a record that, perhaps unsurprisingly, has never been attempted before – at 96.39 seconds.

He also broke the record for the fastest time to solve a Rubik’s cube while hanging upside down, doing so in 15.84 seconds to better the previous mark by more than a second.

By comparison, the record for solving a Rubik’s cube while upright is 4.22 seconds and actually held by Aussie Feliks Zemdegs.

The inverted record was more of a physical feat than Jianyu expected, admitting he would need to work on his leg and core strength in the future.

This is far from the first time Jianyu’s cube completions have captured global attention.

In 2015 he appeared on German television program Superkids and solved a measly two Rubik’s cube with his hands and feet.

But his piece de resistance came last year on Chinese TV, when he solved three of the Hungarian puzzles … while juggling them.
