Rubik’s record-breaking teen reveals his secret

A 14-year-old boy who solved a Rubik's Cube in 4.904 seconds says he wants to solve the puzzle faster.

Lucas Etter shaved 0.35 seconds off his friend's record at the River Hill Fall 2015 competition in Maryland, USA.

The time, recorded by the World Cube Association, is awaiting official verification as a world record.

After revealing his secret to Radio 5 live's Phil Williams, Lucas said he wanted to keep reducing his time "just as fast as I can go".
