Jokari Fizz-Keeper Pump Cap

Product Information

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. 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 ] 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. [1] [2] [3] [4] By using the Fizz-Keeper Bottle Pump (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.

Big Clive has a running series on YouTube, “ Will it Carbonate”, where he tries various beverages in a SodaStream machine: here is a playlist. 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.)a b c d Reed A. Howald (Feb 1999).

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.

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. This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below.

By using the Fizz-Keeper Bottle Pump (in conjunction with a water-filled soda bottle and pipet), students can plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object.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] So then, if the air is pumped into a separated area inside the bottle, preventing the diffusion between CO2 into N2+O2, such modified Fizz-Keeper would work, correct? 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.
