Most people would struggle to solve a Rubik's cube in a few minutes, let alone a few seconds.
But Lucas Etter is not most people. The 14-year-old is special as he showed at a competition in Clarksville, Maryland.
The American teenager solved the cube in a jaw-dropping 4.9 seconds to break the world record!
The previous record of 5.09 seconds had been set on the same day at the same competition.
Contestants get 15 seconds to examine the cube before solving it.
