Question for the scientific types.....
I fill my ice-cube trays with filtered water, and then put them into my freezer.
For some reason, the water freezes in spikes.
Pic attached.
Why is that. Never seen it before. Very curious as to how this can happen.

Oh, and btw.... (note to site admin)....
You really need to sort this bloody pic size thing.
Cameras have evolved a hell of a lot, and making a file fit into the 100KB or the 800 x600 pixels thingy is unrealistic.
I have to redo my pictures 4 different ways just to get them on here! And I'm sure I'm not the only one.
 
Thanx for the link..... My google is not a happy place today.
Interesting that it's the type of water too. I thought it might be relevent, which is why I noted it in my op, but I didn't know why.
:)
 
I blew the pic up and it looks like the water is freezing along what appears to be a rat hair...
 
and here I was thinking it was cuz you were preparing those trays sans clothes and it happened to be the male cubes

Lol - that might explain one spike, but I had 4 trays and each cube had a spike!
But I seriously don't believe there's a hair.... I use a charcoal filter and my house is spotless. I might live in the country, but I clean obsessively. And CadburyCat takes care of all the vermin before they get in.

The filtration removes impurities just putting it short of distilled.

Our freezer has an ice maker so we just get half-moon ice ice pieces...

The spikes are formed as micro-anti-gravity pockets float over the ice tray in the freezer. It's a little known fact that the modern freezer creates these tiny pockets of anti-gravity, but ever since the very first freezer was invented in 1465 these spikes have formed and been noted by a leery populous.
 
Caltech didn't talk about subcooling at all so I believe their reasoning for the ice spikes to be slightly flawed.

It's not a spike. It is a fin. You have cube sharks. Be careful when the cubes thaw.
 
Water is the only thing on earth that expands when it becomes a solid.

Does anybody understand the ramifications of this.

What would happen if water contracted when it froze and became ice.

I find it quite strange that water is the only thing that expands
 
"Cube sharks".

I think this is the coolest explanation here.

The truth is just as cool, but everything is better with sharks.:D
