Documentary Of A Pepsi Bottle Under Pressure
The following photos should help you understand how a PET bottle bursts
You can pop a Pepsi bottle with a keyboard dust blower from places like this and from office supply stores. PET bottles are designed to withstand internal pressures up to 200 PSI. That's 3-4 times the pressure in most soft drinks. The soft drink bottles you see sitting on the supermarket shelf are pressurized to 55 PSI. Pick one up and squeeze it. They're pretty darn hard. Trillions are bottled and sold each year.
A Fizz Giz Soda Maker Cannot Pop A PET Bottle - Period!
The Fizz Giz has a built-in pressure regulator limiting the delivery pressure to only 55 PSI
at room temperature.
That's a safe limit used by most soft drink bottling companies.
