Today's interesting fact has to do with water.

Specifically water bottled in plastic.

To understand the cost of bottled water, it has been estimated by various orgnaistions that to bring home the cost in oil, the bottles should be filled with a specific amount of oil.

How much, oil there should be depends on if the company estimating it is funded by producers of bottled water or not.

It can range anywhere from a fifth of a bottle to a quarter of a bottle of oil.

The cost doesn't just come from the manufacture of the bottle, but also to the filling of the water, the pumping of the water, the transportation of the water, and in many cases the filtration, of the water.

Some water is purified by removing everything except the water, and then adding specific chemicals to give the perfect taste.
