Wild Experiment Reveals What Would Happen if You Touched
WEBNov 2, 2023 · An experiment has finally revealed how it might feel to touch a quantum superfluid. Physicists dunked a special, finger-sized probe into an isotope of helium cooled to just a smidge over absolute zero, and recorded the physical properties therein.

Superfluidity - Wikipedia
Superfluidity is the characteristic property of a fluid with zero viscosity which therefore flows without any loss of kinetic energy. When stirred, a superfluid forms vortices that continue to rotate indefinitely. Superfluidity occurs in two isotopes of helium (helium-3 and helium-4) when they are liquefied by cooling to cryogenic temperatures. It is also a property of various other exotic states of matter
