"Lets put it another way," says the narrator, "there are more atoms in a single glass of water than there are glasses of water in all the oceans of the world. It sort of hurts your head just to think about it."
"the atom is almost entirely made of empty space."
"If you were to suck out all the empty space from every atom in my body, then I would shrink down to the size smaller than a grain of salt. Of course I'd still weigh the same."
