FOR most of us, it can take a lifetime to master the Rubik's Cube.
Not even Erno Rubik, the cube's inventor, could solve the puzzle at first.
But for 10-year-old Ryan Smart, solving the randomly scrambled puzzle is simply a flick of the wrist.
In a matter of seconds he can click and twist the cube into coloured sequence, moving his hands at such pace it almost looks like magic.
Now Ryan has taken his talent to the Mooloolaba Esplanade, captivating crowds with his pace.
"I use busking to practise and each time I get quicker and quicker," he said.
"At first it took me ages, but now I can solve it in under a minute."
The Caloundra sixth grader taught himself to solve the puzzle in September last year and began busking a short time later.
His average speed now stands at 64 seconds, with a record time of 54 seconds.
Now Ryan wants to take his skills to the next level by solving a five by five Cube, and in the same time as one half its size.
"I just have to keep practising when I can, but I haven't tried the big one in front of anyone yet," he said.
"It is a challenge that I really like, it is fun and people get pretty amazed when I do it in public."
And the Rubik's whiz's favourite subject at school? Mathematics, of course.
You can catch Ryan down at the Mooloolaba Esplanade this Saturday night from 6pm.
