From time to time, a long spur of ice grows on one “cube” of my ice cube tray.
It’s quite slender, about 3mm or 1/8 inch at the base tapering to about 1mm at the tip, but it’s about 30mm or over 1 inch long!
The angle of the spur seems to always be the same - about 45 degrees.
What going on here? It seems to defy gravity!
Probably relevant: I seems to happen when the ice tray is placed near the chilled air outlet of the freezer.
Plain tap water.
