Some Greasy Molecules

a: Graphite ~
b: a slip and slide

What: Both things have 2 surfaces that move against each other with very little friction. The slip and slide is a long skinny piece of plastic that gets coated with water. The plastic plus water plus human body make for a very slippery surface. The planar molecules of graphite move past each other, at the molecular level, because the molecules are essentially flat and have broad flat surfaces that slide past each other.
