As strange and unique as the laws of the quantum realm appear in our everyday experience, every now and then experiments catch sight of phenomena that seem both alien and yet eerily familiar. For the first time, droplets have been seen shattering into a ‘quantum rain’ in a degenerate, ultracold fluid of potassium and rubidium isotopes, bridging the classical world of fluid dynamics with the ethereal landscape of atomic gases.
