Reduced water surface tension?

Anyone think this will do the job without adding a lot of unecessary chemicals to your loop?

nanominerals that reduce surface tension eh?
I would pass (but I just use antifreeze and don't worry about it)

Doesn't soap also reduce the surface tension of water?

I remember the experiment where you dipped a pin is soad the touched the pin to a small drop of water then the drop would "expand" laterally over the surface. I may be wrong, chemistry isn't my field/

I know that fire depts sometimes add surface tension reducing agents to water so it's better at putting out fires - and farmers sometimes do the same to improve root water uptake - but I have never heard of doing this to drinking water to improve cellular water absorption.
I suppose that if I have a bacterial infection I should drink bleach? IMHO, the same sort of reasoning...
There may actually be some beneficial effect - although I'd guess it was more in just getting folks to pay attention to getting hydrated.
Not that I'm any good at it - particularly when I'm traveling on a motorcycle. I stopped at a snack bar at the end of one day, bought a liter container of lemonade, drank that, bought another, drank half that and finally decided I'd had enough. Wonder how close to dehydrated and stupid I was (erm... make that "dehydrated and more stupid")...?
