One Bend, Six Consequences

Water is two hydrogens and an oxygen, and the whole of Unit 1 leans on the angle between them. Because the molecule is bent and oxygen pulls harder, one end goes slightly negative and the other slightly positive — and that single structural fact is why water climbs trees, holds up a strider, keeps your cells from cooking, and freezes into something that floats. Watch it happen. Then watch the one bond students always misplace get put back where it belongs.
