00:30Soap!

00:32Soap has a split personality.

00:34The head of the soap molecule is made of an alkali,

00:37and its body is made of fat.

00:39Yes, fat.

00:41Dirt is also made of fat.

00:44Water and fat don't mix.

00:47But when you wash,

00:49the fat in the soap grabs onto the fat in the dirt,

00:52and its alkaline part sticks to the water.

00:54So soap forms a link between the water and the dirt

00:58and rim moves it.
