Watch: Usain Bolt can do other things fast, too

Watch as Usain Bolt displays some hidden talents, all of which involve speed.

Usain Bolt is fast. Really fast. Not a secret. 

But when the six-time Olympic champion sprinter from Jamaica caught up with SI Now, he decided to display some of his other talents. All of which are things he can do fast. Very, very fast.

From Rubix cubes to chess to...making grass grow, take a look as Bolt and SI's Maggie Gray put his skills to the test. They don't give out medals for these things, but he was into it anyway. 

Whatever you do, don't blink.
