Perfect to use with Cartesian Diver experiments.

Description

Designed to keep the carbonation in plastic soda bottles, these pumps are perfect for Cartesian Diver experiments. Simply place your diver in a plastic soda bottle filled with water, screw on a Fizz-Keeper Pump cap, and pump away! With this pump, even young children with small hands can easily operate the diver.

so many experiments!

Aug 5, 2018

We placed these in a bottle with the liquid crystal thermometers to show the relationship between temperature and pressure, created a cloud in a bottle, took the mass of the bottle pre pumping and after 25/50/100 pumps. (would have given 5 stars if they all worked.)Teachers LOVED them.

Works great for Air Pressure demos

Sep 6, 2015

I use this pump on a small water bottle that is filled with mini marshmallows. With just a few pumps, the marshmallows begin to cave in and shrink. Once the top is opened they pop right back into shape. This shows the students the power of air pressure on an object. We used it to discuss pressurized cabins in air planes. Also, letting the students take turns pumping the cap they can "feel" the air pressure building. That is huge for them.

Cool toy! Will use with Pre-AP and AP chem demos!

Fizzkeepers are keepers:)

Oct 15, 2014

I added a Fizzkeeper section to my lab on "Is Air Matter?" for "Does Air Have Mass?" The difference in mass between before and after 40 pumps was very effective for 6th graders.

I have owned the fizz keeper for about 10 years and it still works. On 1-liter bottles I have to trim off the seal ring so that the fizz keeper can screw down tight and be airtight. It works great and keeps the fizz for days or months. Of course, the more times I reopen the bottle, the more fizz I lose, but the fizz keeper makes fizz last lots longer.

Great for marshmallow experiment!

May 31, 2012

The Fizz Keeper slows down the rate at which dissolved CO2 comes out of soda...but only over the course of hours, not days. For a fun science activity we placed some marshmallows in an empty 18 fl oz plastic bottle and watched them shrink as we pumped. Be sure to point the cap away from people and unscrew it slowly or it will pop loud enough to scare everyone!

Fizz Keepers Matter to Marshmallows

May 29, 2012

These aren't just for cartesian divers, they can actually help you show kids that air has mass and volume. Throw a handful of mini-marshmallows in a 1 L bottle, find the mass (including the pump), have the kids pump away... I won't spoil the surprise, but it is fascinating and kids will always remember air is matter! If you have older kids, they can actually find the density of air (if you are ok being off a power of ten or so..)

Pressure keeper holds up to its name

May 16, 2012

I purchased this product to demonstrate air pressure. I placed marshmellows in a soda bottle and the scouts pumped in air until the marshmellows decreased in size considerably. Now I use it to keep my soda from going flat. It works beautifully!

Fizz-Keeper Pumps Are Great!

May 16, 2012

I use these pumps for all kinds of things. Anytime I need to have a pressure difference, I grab one. They can be used to demonstrate manometers, ideal gas law, Pascal's principle, adiabatic expansion, etc. I cannot have enough of these.

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

Elementary

Middle School

High School

K-PS2-1

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 compare the effects of different strengths or different directions of pushes and pulls on the motion of an object.

3-PS2-1

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.

3-PS2-2

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.

MS-PS2-2

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.

HS-PS2-1

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.

Suggested Science Idea(s)

The Fizz-Keeper Bottle Pump is designed to attach to the top of a one or two-liter plastic soda bottle, this pump is perfect for Cartesian Diver experiments. With this pump, even young children with small hands can easily operate the diver to best understand how changing pressure on the water and density of the diver affects, as water is forced into the pipet (diver).

K-PS2-1

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.

3-PS2-1

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.
