You're listening to Brains on.

When we're serious about being curious.

When you wash your hands, there's a battle going on.

One between the soap and the dirt and germs on your skin.

It's a nasty fight with brutal attacks.

And no mercy.

The soap wins and the dirt and germs lose, big time.

But how?

Yeah, what exactly does soap do to cross those filthy foes?

Turns out, soap has a special design that makes it the perfect thing to kill germs and clean dirt. But to see how it works, you have to zoom in super close.

Which is exactly what we're going to do.

Keep listening!
