Superfluid

Superfluidity is a unique state of matter that occurs at extremely low temperatures, where a fluid can flow without viscosity, meaning it has no resistance to motion. Imagine a liquid that can move through tiny openings or over surfaces without losing any energy. This phenomenon occurs in materials like liquid helium when cooled near absolute zero, allowing them to exhibit remarkable behaviors, such as climbing walls of their containers or flowing without friction. Superfluidity reveals fascinating insights into quantum mechanics and the behavior of matter at a microscopic level.
