Should the US ban foreign bottled water into the US?
It seems like a huge carbon footprint. For just moving water around.
When the US has some of the best water on earth, anyway.

The US doesn't need to ban bottled water as much as we need to get consumers to give it up on their own and take tap water.

Free learning from The Open University www.open.ac.uk --- Have you ever wondered where bottled water comes from and what impact this has on the ...

The sensation is suction, meaning the mouth of the glass bottle stuck to my hand. I know it this has something to do with pressure build up from 2 minutes of shaking carbon dioxide gas and water in the bottle, but am not sure exactly why.

Carbon dioxide is "soluble" in water. It isn't actually CO2 when it is in water, instead it reacts with water to form carbonate and carbonic acid, which are soluble in water. You know from experience that it helps to agitate water (stir it, shake it, swirl it) when you're trying to dissolve anything in it. I mean, you stir cool-aid to dissolve sugar, don't you? So if you shake the bottle, you'll aid in dissolving the CO2 faster.

The next question is: what is it that creates suction? Well, a vacuum does. So then, what is a vacuum? It is a LACK of atmosphere. When the CO2 goes into the water, you're reducing the pressure inside the bottle by removing the atmosphere. This creates a vacuum, which produces suction against your palm.

So the buildup of pressure inside the bottle is not what creates suction. I can see why you think shaking water and CO2 will build up pressure though, because if you shake a bottle of soda pop, you'll build up great pressure in the bottle. That happens because soda pop has excess CO2 already dissolved in it and shaking the water brings the CO2 out. Shaking non-carbonated water under a CO2 atmosphere dissolves CO2 instead of bringing it out.

Price: $19.99

3/4-inch inlet/outlet for installation on main cold water line
5-year limited warranty
Extends life of washing machines, hot water heaters, and other water-using household appliances

The bottle water of course has water in it (tap water)
and that will it have any difference with one that was not covered with carbon paper....
both bottles are of the same size and type (glass bottles)...
and the carbon paper is outside not touching inside of the bottle...
will it, by any chance, have less ions since it has been in isolation, unmoved for a month???

if the permeability of the bottle has big enouph pores for the carbon to get trhough then yes. not only that....the top of the water bottle will have carbon.....making it taste nastly like lead

So, drinking a glass of bottled water leaves a carbon footprint 600 times bigger than that of it´s tap born counterpart.
Therefore we Evian drinkers are guilty of ozone damage on a shocking scale.


Which leaves me with a bit of a dilemma ..cos tap water tastes horrible......................

What do you drink?

I wouldn't dream of buying bottled water. The stuff that comes out of the taps here in Glasgow is perfectly OK for drinking.
Evian water, like cocaine, is nature's way of telling you that you've got too damn much money!
