Good question! I've noticed that too. Apparently it's due to water freezing quickly and impurities in the water. This link may help explain.


All water contains dissolved salts & other impurities.

These end up being concentrated in the last part of the cube to freeze, which is the middle

The middle part is colder and more frozen than the rest of the ice cube.
