Weird Ice Cube |
My brother was making ice cubes in my fridge for 1792 (Whiskey). One
cube grew an upward rod that ended in a point, about an inch high. My
brother likes to see things like this as signs that our dead dog is
sending a signal, but I told him it probably has something to do with
impurities in the water. Can someone explain this?

They're known as ice spikes, caused when freezing is relatively slow. The
surface of the cube freezes apart from a small hole, and the bulk of the
water in the cube expands through the hole and freezes into a spike. As the
water continues to expand the spike gets longer.

I've seen similar in woodland where leaves and bits of moss have been lifted
a couple of centimetres off the surface by spikes - now THAT is weird!

Yes. The explanation as to why your brother sees things that way is:
he is a woo-woo.

***{No. I've seen those spikes myself. They rise up out of the centers
of ice cubes. The likely reason is that the cube freezes from the
outside in. That means there is a reservoir of liquid in the center of
the cube as the outside freezes. Since water expands as it freezes, the
liquid in the center gets squeezed tighter and tighter, and eventually
pushes out through the point of least resistance. That point is usually
at the top of the cube in the center. Only in that way can the pressure
be relieved. Naturally, as water oozes out, it freezes around the edges
of the opening so formed. Result: a little volcano type of structure
arises there. That's how the spikes are formed. --MJ}***
