Please, someone explain this to me: for the second time in a month, there is a strange growth on my ice cubes:
It's a near-verticle sliver extending upwards. I filled the ice cube tray with water (cold water, I think), and put it in the freezer about 2-3 hours ago. I happened to look in and found this, which is similar to one I saw a month ago, though that one wasn't as long.
Here's another view:
The only thing above the tray are some frozen pieces of chicken wrapped in aluminum foil -- well frozen, since I put them in about two days ago. I don't see any drips from them.
As you can see, there is another, smaller growth in the front left of the tray:
What the heck is going on?

Is that repeatable? The aluminium foil above might consentrate the thermal radiation from the freezing process back to that one spot. I've seen some bumps in ice cubes but nothing that big.
It's not very repeatable -- it happened once about a month ago, but doesn't usually happen.
I should take out the foil packages, just to be sure, and keep filling and refilling the ice cube trays to see if I can get it to happen again.
Its a known thing, though as you say, rare. There's a wiki page :-)
