Why would this ice cube freeze in this fashion? I refilled my ice cube tray, put it in the freezer. When I came back a couple hours later, I noticed a slender vertical spike protruding from the center of the ice cube. What would cause the water to freeze in this manner?

Reply	Jon-Richfield says: Well actually Kerouac, I am bothered: Is that a hollow I see on the lower left hand side of the cube's surface? John, can you tell us? Certainly the spikes are common, but in combination with a hollow??? Jon (no votes) Tags: ice, Freezing, Expansion, Hydrophobic.
