Re: Manly saltwater caps
Chris,
Got some bad news - the water jugs are most likely made from either
Polycarbonate or PET (Polyethylene Terephthalate). However, some large
chemical bottles ARE made from polyethylene - these will be a milky or
creamy white translucent color. Polyethylene is never clear.
And yes, the water forms one of the "plates" of the cap.
