Jokari Fizz-Keeper Pump Cap

Product Information

The first Fizz-Keeper-like device was patented in 1926 by G. Staunton. T.R. Robinson and M.B. Beyer patented the Fizz-Keeper itself in 1988, without claiming in the patent that the device maintained a soft drink's carbonation. [2] As I noted in comment #2 above, carbon dioxide is more than ten times as soluble in water than nitrogen and four times as soluble as oxygen, so far more of it can be placed in an aqueous solution. Since much less of other gases can be dissolved, they would impart only a very weak fizz and would not add the flavour of carbonic acid. By using the Fizz-Keeper Bottle Pump (in conjunction with a water-filled soda bottle and pipet), students can make observations and/or measurements of an object's motion to provide evidence that a pattern can be used to predict future motion.

Students can plan and conduct an investigation to compare the effects of different strengths or different directions of pushes and pulls on the motion of an object by changing the number of pumps on the Fizz-Keeper Bottle Pump. I’m not sure how that would work. The problem with the pop going flat is that every time you open the cap to pour some out, the CO₂ above the liquid escapes and is replaced by air and then, after you replace the cap, more CO₂ comes out of solution to replace it. So to keep that from happening, you’d like to find a way to pour out the liquid without losing the CO₂ gas. One way to do this might be to have a cap with a valve in it you could open to pour the liquid. To fill your glass, you’d invert the bottle, open the valve, and then squeeze the bottle to dispense the liquid. When you inverted the bottle, the CO₂ would go to the top, and since you were squeezing the bottle, no air would enter. (These bottles are made from polyethylene terephthalate (PET), which is very flexible, so squeezing should be no problem.) This article needs additional citations for verification.

The solubility K of different gases in water (which I’ll assume is the same as the liquid in the bottle) varies widely, so the behaviour of the gases involved is very different. Here is the solubility of the three main gases we’re dealing with here, all for 5° C, the temperature of a typical refrigerator, and all in units of grams of gas per kilogram of water.

The Fizz-Keeper Bottle Pump using in conjunction with a water-filled soda bottle and pipet, allows students to pump pressure into the bottle to observe and understand the effects of balanced and unbalanced forces on the motion of the pipet. The Fizz-Keeper Bottle Pump, used in conjunction with a water-filled soda bottle and pipet, offers students a chance to investigate and analyze data to support the claim that Newton's second law of motion describes the mathematical relationship among the net force on a macroscopic object, its mass and its acceleration.Research into the Fizz-Keeper's mechanisms and processes has shown that the Fizz-Keeper, let alone pressurizing a soda bottle, does not actually prevent loss of carbonation, with its marketed claims being dismissed as pseudoscience.

Beyer,"Pump closure for carbonated beverage container",issued 1988-02-09 Several styles of device exist, from the plain piston pump to devices incorporating a bulb and a latch and hinge device to allow liquid to be poured out of a spout without removing the Fizz-Keeper from the bottle.
