The Mind-Bending Properties Of Superfluid Helium

The Mind-Bending Properties Of Superfluid Helium

At super low temperatures, liquid helium keeps MRI machines and particle accelerators cooled and running. Just a few degrees above absolute zero, superfluid helium getz bizarre. A superfluid liquid is one that flows without friction. Because superfluid helium has zero viscosity, it can drip out through molecule-thin cracks in solid containers and climb out over the sides of a dish.
