Making Ice Cubes and the Titanic?

I was looking for something to write about while I was taking the ice tray out of the freezer. I've had this silly goal lately to see how big I can make those ice cubes. I'd found that bigger ice cubes will melt more slowly in our Thermos during the day than a bunch of smaller cubes. The trick is to see how much water I can put in the tray without spilling it when I stick it back in the freezer.

Well, this time I just had to show Art what my accomplishment for the day produced.

Isn't it amazing?

I just think it's awesome how water will expand out of its compartments when it turns to ice.

I got this from the Dutton Institute.

"Water expands when it freezes making it less dense than the water from which it freezes. In fact, its volume is a little over 9% greater (or density ca. 9% lower) than in the liquid state. For this reason, ice floats on the water (like an ice cube in a glass of water)."

Wow! It's incredible to think it becomes less dense when frozen and floats in water. 

Gee... I thought. This is so interesting. So it's hard, but it's less dense? And it floats?

I turned to Art and told him, "Did you know that ice would float in a glass of water?"

He burst out laughing. 

When he could catch a breath, he said, "Titanic?"

"Titanic?" I asked.

"Icebergs?" he laughed.

🙄

How embarrassing....

"Please don't tell anybody that you asked me that," he said while still laughing. 

Ahhh well... I'm telling you. I'd better stop writing blog posts for today. I think my brain stopped working.

POSTSCRIPT: 

Uh oh... he just came back to tell me, "And did you know that fresh water will float over salt water because salt water is denser? That makes icebergs float even more so."

I'm leeeeaving.....
