Strange Ice Formation

[ZeeOSix]

Water put into a clean empty yogurt cup and put in the freezer. First time I've ever seen the ice grow straight up off the surface. What's the mechanism here?

I've seen these in ice cubes: http://www.its.caltech.edu/~atomic/snowcrystals/icespikes/icespikes.htm but never one as large as that

Looks like air bubbles got trapped just right and rose as the water froze. I'm pretty happy with it. Why are you freezing yogurt cups of water?

It's happy to see you! (sorry, couldn't resist).

Male water!

Stalagmite ice....but I know it's not. Very interesting!

Is this for the Punch Bowl? Only thing I can think of is the water in the centre being forced up by the expanding ice around the surface circumference of the cup

I like it. And since it was forcing it up in the center, it kept the center from freezing as the water was slowly moving upwards as the expansion was forcing it to the weakest area.

There are circulation fans in modern fridges so the air currents could have contributed something. ZeeOSix stuck a hunka icicle in the water to have us on.

Slow drip from above

Yeah. that's the only time I've seen that stalagmite - like formation , usually outside, formed during Winter from dripping water from the roof.

Top layer froze first except for a hole at center of formation relieving pressure of expanding ice from below.

T-1000 was about to ruin your day, but fortunately froze before it was too late...

LoL ... it does look like that. I've made big ice cubes like this for over a year (I like one big piece of ice in my glass), and this is the first time I've ever seen this happen.

Thanks for the link ... makes sense.

That's a poor excuse for imitation banana flavor.
