Welcome to the Dead Sea, where the beach is covered with perfect little cubes of salt.
This video is incredible, but the science behind the phenomenon is even cooler.
As Chemical Refraction explains over on Reddit, these cubes form because of the geometry of the salt’s chemical bonds - since the surface is exposed to the same concentration of salt in the Dead Sea, the cube grows symmetrically.
So what about all the salt chunks that aren't perfect cubes? It's hard to know for certain, but it's possible these structures contain impurities that have disrupted their formation.
Pretty freaking awesome.
