Liquids that are less dense than an ideal gas - PHYSICS

A water droplet has structural integrity because of attractive forces between water molecules. If the molecules get close enough, however, the intermolecular forces are repulsive; water molecules can pack only so tightly. In quantum systems, intrinsically quantum fluctuations can stabilize a cluster of atoms against collapse. As a result, quantum droplets can have extraordinarily low densities.

Using Bose-Einstein condensates, researches created liquids that have extraordinarily low densities - five orders of magnitude below that of an ideal gas at room temperature and pressure.
