Who cares?!? Ice is ice. I defy them to compare a cube of their to one from my freezer and tell me the difference.

That's actually quite easy. Glacial ice has bubbles of air under pressure in it. If you put it in a glass of water, as it melts it pops and fizzes, and is supposedly very entertaining. (I've only heard this, haven't actually seen it demonstrated.)

I was just thinking, "Can I use that ice to keep my Dewar's and water cold?"

Wow, cool -- so the ice in your freezer contains captured pockets of atmospheric air from hundreds of thousands of years ago, ancient pollen grains from extinct plants, layers of dust from pre-historic volcanic eruptions, and micrometeorites from across several millennia?

I'm impressed.
