Almost any liquid can freeze -- aka: change from a liquid to a solid -- but some of them taste a lot better than others. The story of the brand "Popsicle" is the story of a kid named Frank Epperson, who accidently invented the frozen treat. He called it an "Epsicle" (he was 11, so of course he did), but his kids referred to the treats as "Pop's sicles" and the brand Popsicle was born.
But, how often do we think about freezing as the process of slowing down the movement of atoms? It all comes down to physics.
Our next Idongetit Science Tale gets deeper into the atomic details of the states of matter.
