The tap in my large-sized refrigerated water filter tank, fondly known as the Brita Keg, has a slow, steady leak. The tap only drips once every few minutes, so I usually forget all about it unless I put something cardboard under the Brita Keg that turns up wet the next day.

But I moved to this new house a few months ago, which meant adjusting to a new fridge, and this one has developed an interesting quirk. I've started discovering little frozen stalagmites of impressive size growing from the floor of the fridge every few weeks.

It took me a while to put two and two together, but I finally realized that it must be water dripping from the Brita Keg, running down to the back of the shelf, and somehow freezing when it drips down to the bottom of the fridge. I'm not sure why it's freezing, since the temperature isn't set drastically low and nothing else in the fridge freezes. It's kind of weird.

I don't think I'll bother trying to fix the leak — the ice sculptures are kind of beautiful. Maybe I'll stop throwing them away when I discover them. I'm curious to see how high this one will grow.
