A clever drinking system for use with standard PET bottles (neck diameter 28 and 30 mm) and widemouth bottles (neck diameter 53 mm). In a flash you can covert your bottle in to a complete and inexpensive drinking system. The straw length can be adjusted to the depth of the bottle and the bite valve is easy to suck through. A one-way valve in the stopper provides the air flow.
