A group of scientists have reported that they created the first-ever helium supersolid, which is both liquid and solid and should be impossible.
Put water in an unglazed ceramic bowl and it will be there tomorrow. Do the same with superfluid helium and it will go right through the bottom.
When we think of uses for helium, most everyone immediately thinks of party balloons, blimps, and high-pitched voices. However, the uses for helium go far beyond just a few novelties. (Never inhale helium, by the way. It can kill you.) In fact, without helium, we may have never had our supermarket checkouts, iPhones, or even the ability to detect tricky cancers.
Below are the different uses for helium that you probably didn’t know existed.
The smallest known vortexes, with cores just an atom in diameter, have been discovered hidden inside tiny droplets of helium.
