This video discusses the concept of quantum tunneling, and how this phenomenon only works because particles can act like waves.

The fastest baseball pitch ever thrown reached over 170 kilometers an hour. That's impressive. But even that record breaking fastball would never be able to pass through a solid brick wall.

It's just not possible. That is, unless we're playing quantum baseball.
A thrown baseball might have enough energy to rip through a piece of paper, but even the fastest pitch would just bounce off a brick wall.

Yet sometimes quantum particles are caught passing through barriers they don't seem to have enough energy to break through.

Logically, they should just bounce off. And yet there they are, sitting quite happily on the other side. How can that be possible?
