Liquids

The optimist sees the glass half full. The pessimist sees the glass half empty. The chemist sees the glass completely full, half with liquid and half with air. The viewers of this video will see the many ways liquids, like the one the glass, are just weird. Beginning with the London Dispersion Forces and dipole-dipole forces, the show then moves into hydrogen bonds, cohesion, adhesion, and viscosity, and concludes with an explanation of capillary action and surface tension.
