Rubik's Cube record-breaking teenager says he still wants to solve the puzzle faster.

14-year-old Lucas Etter broke his friend's record by solving a Rubik's Cube in 4.9 seconds at the River Hill Fall 2015 competition in Maryland, USA.

The world record time is being verified by the World Cube Association.

The speedcubing teenager says 'There are many tutorials online' and a distinct set of methods to use when attempting to solve a Rubik's Cube.

Lucas says "Speedcubing means I can socialise with like-minded people, so I have friends from all over the world". He says he wants to keep reducing his time "just as fast as I can go".
