Upstate researcher solves ice cube mystery
In emptying an ice tray one recent morning, I came across this bizarre ice cube, with a cylinder or thin tower building upward from its base like a stalagmite you would find growing upward from the floor of a cave. I posted a picture of the mystery ice cube on Facebook, receiving only silly suggestions of the cause. So, I took a stab at getting a real answer from a real scientist. Dr. Luo was fresh on my mind, as he had recently consented to appearing in the magazine I edit, Upstate Health. He's busy creating new ways to get cancer drugs into tumors -- but he kindly took a short break to ponder my ice cube mystery.
If there was no water dripping from the top of the freezer -- and I checked that there wasn't -- Luo theorized that some "impurity or dust in the water induced a highly ordered crystal of water." The vapor water molecules continuously grew at that one site, in that same direction. "Eventually it forms a stalagmite," he said.
So...I think that means the ice tray needs cleaning!
