How to Freeze Water

I've been contemplating switching to metal ice cube trays instead of the plastic i currently have.

I googled the topic.

Didn't realize that so many others were having these discussions:

Debra Lynn Dadd has a pretty thorough Q & A on the topic

so most metal trays are Aluminum. makes sense. I'll look into it - eventually. But i got distracted by other things...

She has an interesting site as well. She's referred to as the Queen of Green. So I'm not sure if it's worth switching over since they say not much harmfull substances transfer over. I don't use much ice but still... you never know when you're gonna want a Bloody Mary.

After pondering this topic - i think i need one. A Bloody Mary, that is.
