Physicists have teased water molecules into a new state—one that has some very peculiar quantum mechanical properties.

For the most part, water on Earth comes in three varieties—solid ice, gaseous vapor, and (everybody’s favorite) liquid form. We’ve all known this since basically forever.

But now physicists, who love throwing monkey-wrenches into things and mucking with our cherished notions of everyday existence, have come up with another doozy—a brand new state of water.
