It is real difficult to find good water these days that's a fact. I have had to work at it a bit. watch out for the flouride in your toothpaste too, and dental fillings.

Oleg, I have on the counter, some eggshells from breakfast this morning... I put them into a small jar, covered them with vinegar, and put the lid on the jar. I figure they are ok not going into the fridge because of the vinegar, kind of like pickles, I don't always need to refrigerate those... but how long do I let that sit there till you would consider it ready to use? Should I shake it a couple times a day?
