Have you ever think of unlearn something that you already mastered like riding bike or driving car? No, right? Or have you ever even know that we can unlearn a thing? I mean unlearn not forgetting it.

Destin, the creator of Youtube Channel of Smarter Everyday, had made a very interesting experiment of how he unlearns to ride  bicycle.
Here's how he did it:
  • First he use the backward bicycle, the same as normal bicycle except the steering, the backward bicycle go to opposite direction as it go left when you steer to right direction.
  • Second, he learns to ride this backward bicycle everyday for 15 minutes for 8 months until he can ride it.
  • Third, he go back to ride to the normal bike and he can't ride it.
And that's how he unlearn to ride the bicycle.

Here's the whole video of his experiment.
