Liquids tend to pull themselves together into droplets due to surface tension. The kinetic energy in a liquid is greater than that of a solid, but less than that of a gas. A liquids atoms/molecules are "slippery"; that is, they slide over one another, allowing the liquid to flow.
If a liquid is at rest, the pressure at any point is given by
It should be noted that glass at normal temperatures is not a "supercooled liquid", but a solid. See the article on glass for more details.
