Jokari Fizz-Keeper Pump Cap

Product Information

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 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 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]

By changing the number of pumps on the Fizz-Keeper Bottle Pump (used in conjunction with a water-filled soda bottle and pipet), students can plan an investigation to provide evidence that the change in an object's motion depends on the sum of the forces on the object and the mass of the object.

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. [1] [2] Description [ edit ] 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. A Fizz-Keeper is a type of closure that is marketed as a way to keep carbonation in soft drinks. It consists of a small round hand pump that is screwed onto the top of a plastic soft drink bottle, which is then used to pump air into the bottle, preventing the drink from going flat.

Big Clive has a running series on YouTube, “ Will it Carbonate”, where he tries various beverages in a SodaStream machine: here is a playlist. The Fizz-Keeper Bottle Pump, used in conjunction with a water-filled soda bottle and pipet, allows students the opportunity 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. 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. 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.
