Me: See ice is crystallized waterAmy at B.Ph.D. had a better explanation
C: What does that mean?
Me: See water is made up of these little things called molecules. When water is cold, they are all tied together, and they get all tied together, the form straight lines, so we call it a crystal. That’s ice. When the sun shines on the ice, it breaks the bonds holding the molecules in straight lines, so we get water.
"It gets too hot to stay together and has to all move around. Ice is what happens when the water gets cold and stands still."Any other ideas?
"Why can't I see it moving around?"
"The little bits are reaaaally tiny. Too tiny to see. All little tiny pieces of water. But you can't see them because they're too tiny. They're moving around, though."
"Yep, in there."
