Our ice freezes up - seriously! Reverse-osmosis water, a normal freezer, and look what we get.

Our Ice Freezes Up

what in the world!??
You’re telling me. I’ve never seen anything like it.
I’m glad I’m not the only dude who sees stuff in his freezer and thinks to blog about it LOL.
Damien - I just think, "Someone has to see this!"
Having a blog messes with what would otherwise be just ordinary thoughts.
that hapened to me
i went on a websight and found the anser It is precisely one of these interesting properties that accounts for its weird behavior during freezing, where the gravity-defying thorns appear.
While most substances contract themselves when freezing (shrinking by decreasing their volume), water does exactly the opposite and expands. That is why a glass bottle of water in a freezer may actually break if not thick enough to withstand the pressure generated by the increasing volume of water.
When a thin crust of ice forms, it can trap a tiny bubble of liquid below. As the freezing goes deeper, the water tries to expand until it reaches a tiny hole in the lower layer of the ice crust.
The bubble tries to go up, but the road is blocked by the hole, so as it begins to solidify, it is forced up through the hole and starts freezing around the edges. Step by step, the droplet shrinks by freezing and the only way the remaining liquid can go is up.
As it climbs, it forms a hollow spike filled with water, until it freezes completely. The spike can grow quite long and thin, as the only energy required to lift the water comes from the expansion of the water itself, during the freezing process.
