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.

It is, they say, the first time we have gleaned an inkling of what the quantum Universe might feel like. And no one had to get horrific frostbite, or ruin an experiment, to find out for real.
