A 20-year old man from the Netherlands has broken the Rubik's Cube world record, solving it in 4.74 seconds - that's less than the time that it takes most of us to even begin.
Mats Valk broke the record at the World Cube Association's Jawa Timur Open in Indonesia on Sunday.
Mr Valk's average time at the competition was 6.89 seconds. His rivals averaged from 10.00 seconds to 17.78 seconds for the same "solve", as it is called in the Rubik's Cube competition world.
Australia's world cube champion Feliks Zemdegs was impressed.
