Apparently agitation is important to keep the particles from joining together. But apparently it's an art in itself. I think magnetic stirrers are good.
"negatively charges water" - I'm not convinced such a thing can be done. What does that mean exactly? You can't give water a net magnetic "charge". There is no such thing as a magnetic monopole. Or do you mean the water would be electrically negative? Again, this is weird. It must somehow involve introducing ions into the water like the H- ion. I REALLY want to make "alkanised" water full of H- ions. Haven't researched it yet though. Thanks for reminding me, I forgot I wanted to make those too.
Bah. I need more hours in a day. I still have a job...
