Introduction: Home Carbonation System...Cheap, Healthy, and Green.

Picture of Home Carbonation System...Cheap, Healthy, and Green.

The cost to convert water to soda water is less than $0.04 per 2-liter bottle,

and a single fill of a 20lb tank will charge over 500 bottles!

Here's a quick demo of how it works...

For those looking for the "Cilffs Notes" summary of how this works: Take a 20lb CO2 Tank and regulator, attach a tube, and stick a 99 cent locking ball air chuck (tire inflator) on the end of the tube. Pop a cheap snap-in tire valve (schrader valve) into a plastic soda bottle cap and you're ready to carbonate any cold liquid in about 30 seconds. Colder liquids absorb more CO2 carbonation.

If you're intrigued, explore the steps on subsequent pages for more details...

I've recently taken to flavoring my soda water with fresh-squeezed lemon juice; when we have a bumper crop I also freeze a bunch of ice cubes of freshly juiced lemons, then take out and zap a cube for 15 sec. in the microwave to throw in my drink...Really tasty, low calorie, and no added sugar...

As far as a "soda substitute," you can easily add a splash of orange, cranberry, or other fruit juice, a twist of lemon or lime, alcoholic mixed drinks, commercial or homemade soda syrups,or whatever you like...Our family drinks a ton of sparkling water; as kids, we always preferred it to regular tap water, and it's much healthier than soda.

I've also experimented, with amusing success, at carbonating cheap wines (read: Charles "Two Buck Chuck" Shaw from Trader Joe's) to make dirt cheap champagne...Just make sure the bottle is chilled first, try not to get any wine (or sugared drinks) in the air hose, and be careful opening it after carbonating!

I had been toying with the idea of buying a home carbonator, but I was leery of the idea of being locked into a proprietary, closed system of buying expensive refill cartridges from a retail manufacturer like Sodastream...

I knew there had to be a better way. After all, this is just mixing CO2 and water.

In my research, I came across an incredibly detailed essay on carbonation by Richard Kinch, without which I could not have completed the project...I highly suggest reading over his opus before embarking on your own carbonation exploration.

All of this can be done for around $100, plus the deposit on a CO2 tank...

Given that the cost of a 2-liter bottle of sparkling water is now over $1 (California just doubled their CRV surcharges), and based on the volume of water that we drink, it's a no-brainer. Plus, there's the feeling of liberation of being able to drink as much sparkling water as you want (much like digital photography vs. wasting actual film).

I'm not an EnviroNut, but since we're all supposed to pitch in and make a last-ditch effort to save the planet, these facts on the effects of plastic water bottles on the environment were of interest:

- Approximately 1.5 million barrels of oil - enough to run 100,000 cars for a whole year - are used to make plastic water bottles, while transporting these bottles to markets burns even more oil.

- According to a 2001 report of the World Wide Fund for Nature (WWF), roughly 1.5 million tons of plastic are expended in the bottling of 89 billion liters of water each year.

- The growth in bottled water production has increased water extraction in areas near bottling plants, leading to water shortages that affect nearby consumers and farmers. In addition to the millions of gallons of water used in the plastic-making process, two gallons of water are wasted in the purification process for every gallon that goes into the bottles.

- Nearly 90 percent of water bottles are not recycled and wind up in landfills where it takes thousands of years for the plastic to decompose.

Personally, it's really just nice not to have to lug a bunch of 2-liters home from the market anymore, carry them all in, and find places to store them. (I'm sure she'll find other chores for me to do soon enough...)

If money is no object, and/or the carbonation system is under consideration for use by elderly / disabled (or simply lazy) individuals, there IS another option that doesn't involve shaking the bottles yourself...

- Purchase a Sodastream (from Bed, Bath, and Beyond with a 20% off coupon, or somewhere even beyond-er), procure a Co2 tank as described above, and purchase a Freedom One (or Freedom One+ system) from to connect the Sodastream with the larger Co2 tank. (choose the CGAWG or CGA option if you're on their order page.) While the initial investment in the supplies is not quite as cheap (about an extra $200), and it's not quite as DIY, I recently set up both sets of my grandparents with this system, and they absolutely love it.

Step 1: Procuring Your Precious Parts...

Picture of Procuring Your Precious Parts...

(see pictures below for the product labels, etc.)

- CO2 regulator, available from,, Amazon, or eBay (likely the cheapest way to go, but make sure you know what you're getting...)

- CO2 Tank; either ask to put a deposit on a 20lb CO2 tank for around $100 at a local beverage supply, bar supply, restaurant supply, soft drink, or beer distributor in your area, OR buy your own...Since you won't get your original tank back when you swap it out for a full tank, I'd recommend purchasing a reconditioned cylinder from or eBay. Regardless of whether you end up buying or putting a deposit on a tank, you can swap out empty tanks for about $15-25. To find a supplier, first check here for the nearest Airgas supplier (a popular, nationwide chain). They're the easiest way to go, possibly a tad higher prices than other places for a co2 tank swap. Otherwise, call around, search google maps for beverage supply, welding supply, home brewery supply, or be creative; Barmade, the bar products company that I found in Los Angeles was very helpful...When I moved, I switched to swapping my empties out with Airgas.

- Locking Ball Chuck, either available at Harbor Freight or Monkey Grip part #M8871, available online or in stores at Kragen Auto testing, users have said that the Kragen/PartsAmerica locking ball chuck wasn't as sturdy as the Harbor Freight chuck...and it's also an excuse to visit the tool mecca of Harbor Freight. (Your mileage may vary.)

- Monkey Grip Rubberized Snap-In Tire Valve part #M4130, available online or in stores at Kragen Auto Parts...

2015 Update:
After completing this instructable almost eight years ago, I've given the original to my parents, and built another one for our new house...Unfortunately, Harbor Freight AND our local auto parts store have changed the design/supplier of the locking ball chuck, so that it either slips off easily while shaking, or simply self-seals at a certain PSI. After doing some research on alternatives, I happened across a carbonator cap from that's not quite as DIY, but slightly more elegant (and slightly more expensive) than the tire valve solution...It works quite well, is very sturdy, and my wife will now be able carbonate water again on her own!

$20 Stainless Steel Carbonator Cap and Locking Quick Release Ball Lock Disconnect

Also, if you're concerned with the rubber snap-in valve leaching into the seltzer water, this may be a good option for you. Based on my research, I have been replacing/swapping out the rubber snap-in valve caps much sooner than they would theoretically start to deteriorate, so it hasn't been a concern of mine over the past 5 years. As a third option, they also make screw-on, stainless-steel-based tire valves, which would result in less rubber contacting the water. I haven't tried these yet...if you end up using the stainless steel ones, drop me a line and let me know how it went !

- 1/4" Threaded Full-Port Ball Valve (inline shut-off valve), available at Home Depot...The part number is 107-701HC; the SKU on the bar code appears to be 32888 07701...

- 10 foot roll of braided vinyl tubing, 1/4" internal diameter, available at Home Depot...The external diameter of this tubing is 1/2"...

- (3) hose barb adapters, 1/4" barb x 1/4" MIP, available at Home Depot...This part is a "Watts A-192" or "A-192/225." Do not get the "192B"...

- (4) 9/16" hose clamps, available at Home Depot...I found these in a package of 10, with a listed "range" of 1/4 to 5/8.

- (3) 3/4" plastic pipe clamps, available at Home Depot...

- roll of 1/2" teflon tape...

- a 2 liter bottle and cap.

Step 2: Hose Assembly...

Picture of Hose Assembly...

Wrap 3" of teflon tape around each of the three hose barb adapters in the same direction as you'll be screwing them in...

Screw 2 of the adapters into each end of the inline shutoff valve, and tighten with a crescent wrench...

Screw the remaining adapter into the Monkey Grip air chuck, and tighten...

Depending on where you want to place the inline shutoff valve, cut your braided hose into 2 pieces with a scissors...

Slip each of the 4 hose clamps over the ends of the braided hose about 1/4" away from the ends, and gently tighten just so they won't slip around...

Push each end onto the barbs on the regulator, each end of the inline shutoff valve, and Monkey Grip air chuck, and FULLY tighten each hose clamp with a flathead screwdriver.

Step 3: Regulators....Mount Up.

Picture of Regulators....Mount Up.

Connect the regulator to your tank with either the wrench that came with the regulator, or a large crescent wrench of your own...make sure that the flat washer (which should have come with the tank) is in place before you screw the regulator nut onto the tank....Don't use a washer if your regulator is made by Taprite...the regulator itself will have a sticker warning you not to use a washer...

(Since I was installing the entire assembly underneath the kitchen sink, I chose to attach the regulator horizontally rather than vertically.)

Step 4: Turn Up the Pressure...

Picture of Turn Up the Pressure...

Make sure the inline shut-off valve is off (perpendicular to the hose), and turn on the tank shut-off valve to full...

After you turn the gas flow on from the tank, adjust the screw until the outgoing pressure gauge (the one above the screw in the picture) reads between 45-50 psi...

Turn off any music, make her go out of the room, turn on the inline shut-off valve (parallel to the hose), and listen carefully for any small hissing leaks...

If you're feeling anal-retentive, submerge the inline shut-off valve and bitter end in a bucket of water and check for bubbling leaks.

Step 5: Put It in Your Pad...

Picture of Put It in Your Pad...

Install the system however it fits in your place!

You can install the tank at any angle, as long as it's not completely horizontal...

I've included pics below of my under-the-sink setup...mouse over the boxes in the images to see my notes...

Step 6: Cap It All Off...

Picture of Cap It All Off...

Drill a small hole in the center of the bottle cap (from the top down), and then GRADUALLY use larger and larger drill bits until you enlarge the hole to 15/32"...1/2" will also work if you only have a limited number of drill bits.

Pull the top of the tire valve up through the hole with a pair of pliers until it pops snugly into place.

Step 7: Cheers!

Picture of Cheers!

Sit back with a beer (c'mon, you deserve it after such hard, diligent work)...

Watch the above 1 minute, mildly amusing video on how to use your newfangled CO2 contraption...

And know that you'll never have to buy overpriced water again. The system should pay for itself in less than 6 months, depending on your water usage; the cost to convert tap water to seltzer is less than $0.04 per 2-liter bottle, and a single fill of a 20-lb tank will charge over 500 bottles...

While you can use tap water, we swap out a pair of 2-liter bottles, refill from a PUR faucet filter, and put it in the fridge before carbonating...the colder the water is before you pressurize it, the more it will carbonate...we also sometimes like to add a twist of lemon or mix it with a splash of orange/fruit juice to keep it interesting.

Again, it's really just nice not to have to deal with so many bottles anymore.

In short, the procedure is as follows...
Fill the bottle 3/4 full of cold water...Burp out the air, and tighten the cap...Attach locking ball chuck...Turn the gas on...Shake vigorously for 20 seconds (it's all in the wrist)...Turn the gas off...Shake for 20 more seconds to equalize the pressure...Remove the locking ball chuck and cap...Enjoy!

If you end up making your own, drop me a line with a picture!

Nice job putting together this Instructable! I've had trouble getting proper carbonation with the 60 psi regulator, even with the water being right out of the fridge. I'm looking for a 120 psi regulator right now, but I was wondering if you have had any problems with your beverages being flat at 60 psi.

Not at all...For how long are you shaking the bottles?

Actually, I already had a SodaStream that I modified to work with the tank. The SodaStream bottles are also proprietary and stiffer, so the technique to squeeze the air out of the bottle wouldn't work. Shaking the bottle is also something i don't want to attempt with the SodaStream still attached. I've found that with the SodaStream mod, you can get away with your method, a higher pressure regulator, a couple of different pneumatic connectors, and an adapter for the SodaStream (~13 bucks on ebay). Your Instructable has been very helpful for me, so THANKS AGAIN!

Ivettesan28 (author)verbatin012017-01-04

Hi, would you mind doing an instructable or posting some pictures? I'd like to try your method!

tflowjr (author)2016-07-31

we use the valved cap and a bicycle air pump to maintain carbonation longer in our home made and store bought sodas.

PlushyG (author)2016-03-09

So, I made this about 3 summers ago now. I tried using it again last night... and though the tank is still heavy and relatively full, it doesn't seem to be carbonating the water. The bottle will feel under pressure, but the taste isn't carbonated at all and there's no bubbles. Also, it's doing this when I change the PSI to 55 (which some people have recommended)... ... but at a lower PSI, it doesn't seem to carbonate either. Ideas?


Zaacharia (author)2015-09-26

I use a quick-release cap from a beer supply place and the connector is standard. I paid $100 for the 20# tank, $30 for the regulator, $12 each for the male and female quick-release connectors. A 20# tank is overkill - it takes me a couple years to go through one. I recommend a 10# tank that will fit under the sink and can be attached to the door or whatever. This is pretty dark but it should give you an idea of my setup.

frkdante (author)2010-06-23

Anyone know if there is a thing as CO2 pills? Sort of like seltzer tablets? If so, one would be able to drop a few in a water bottle.

Zaacharia (author)frkdante2015-09-26

dry ice - aka frozen CO2

lukeyj15 (author)frkdante2011-04-07

Dry ice?

pirateINDUSTRY (author)lukeyj152013-11-21

Available at Ice Creameries, certain grocery stores. It's frozen CO2, it doesn't melt - it sublimates into gas.

pcooper2 (author)frkdante2013-05-15

Chunks of dry ice will work, but it's relatively expensive, and if you drop it into a PET soda bottle and tighten the cap, you have little control over the peak pressure. The results would be bad for your health and others around you if the bottle should burst. Moreover, dry ice is very cold and will result in severe frostbite injury unless handled with tongs. It's much safer to work with a regulated gas supply from a cylinder.

urbanpirate (author)frkdante2011-02-08

you could use a tiny bit of yeast in a sealed bottle but be very careful, unattended for long enough and it WILL explode

GeoffwaG (author)2015-06-29

I just finished setting up my rig and everything works perfectly. My next pursuit is to make smaller bubbles like that Italian water that is served in glass. Any tried and true ideas? Thank you in advance. Peace.


roystonlodge (author)2011-02-10

Wondering if anybody's ever tried using a CO2 tank from a paintball gun.

GeoffwaG (author)roystonlodge2015-06-29

1) It depends on your level of paranoia. When you finish filing it's safest to keep all the pressure in the cylinder when not in use with all controls at zero, better if the tank is supported and can't fall down.

2) Had the same problem then pulled the collar back on the female end before installing, like uninstalling but in reverse.

misfist (author)roystonlodge2011-02-10

Yes, this can be done; however, you will likely need some kind of an adapter.

Most paintball canisters have a pin-valve, with which a regulator won't work. The simplest solution is to get a specially-made paintball to CGA 320 (or paintball to regulator) adapter.

Here are a couple links:

Good luck!

MDavisUSF (author)2015-01-25

I cant find a stainless steel schrader valve (tire valve) anywhere I have looked all over. I have the chrome plated ones however after about a year and I made some lemon drinks in them the chrome plating fell off into the water and the bottom of the cap is rusted.

KellyCraig (author)2015-01-14

I lucked out and picked up a twenty pound CO2 bottle with a gauge and a valve for five bucks at a garage sale. Starting there, I ordered the Carbonator cap and the quick disconnect it connects to via Amazon. Then, with a ten foot, clear hose and couple clamps, I was off and running.

It cost me eleven dollars to swap the bottle for a full one. Sure beats the price I paid for a Sodastream refill (around twenty dollars). Too, I get better results carbonating drinks, and can carbonate anything I want.

In the end, the price of everything would have cost me about the same as the Sodastream, a few bottles and four refills. Of course, the refills only give you about sixty charges, versus nearly a thousand with a twenty pound tank.

Thanks for being part of the collection of information which got me going. Now my Sodastream sits on the counter, waiting for me to list it on Amazon.

armorer243 (author)2014-12-28

Also a little hint for everybody, if you have a fire extinguisher supply/service business they will have CO2 tanks and be able to refill them. I purchased (not rented or leased) my 20# bottle for $15, refills cost me $4. I own the bottle and can resell it if I ever want to.

armorer243 (author)2013-10-25

Instead of the quick-coupling tire inflation chuck, I used a Prestacycle Schrader Hose Barb fitting, found here:

Clamps to the hose, screws into the schrader valve. Presto. I used some nickel-plated screw-in valve stems found at Advance Auto Parts for $4 per two-pack. No rubber flavor or risk of corrosion. Works great.

A little side note, I am having trouble when carbonating some fruit juices, they seem to want to foam like crazy when I unscrew the lid. Any suggestions?

rhkramer (author)armorer2432014-12-28

Sodastream (I got one for $5 at a yard sale with most of the bottle of CO2 and 4 bottles) recommends carbonating only plain water, then adding the flavoring when served.

In Europe, I found a lot of people who poured half a glass of juice and then added half a glass of carbonated water.

verbatin01 (author)2014-11-29

You are totally on the same page as I! I wasn't going to spend the money with the SodaStream refills, either. So I did some poking around on the Internet and ultimately ended up going in a similar direction. I just received a brand new 20 pound tank this weekend and need to get it filled. So far everyone is closed for the Thanksgiving weekend, so I'm a little anxious!

MichaW (author)2014-10-19

i found this item very helpful!

Wingloader (author)2014-10-01

No comments below? Holy crap! THIS IS AWESOME!!!!! I just starting drinking flavored seltzer water and it runs about 3.50 USD for 12 cans. I drink a LOT of it. This is going to save me a freakin fortune! It will probably pay for itself in about 2 months at the rate I drink this stuff. Your under the sink installation is something to be proud of. Very nicely arranges and out of the way.

ayushgarg (author)2014-06-16

How do I overcome pressure leakage from the bottle cap?

skyline7349 (author)2013-08-08

I have this setup right now with the carbonator but it has be wondering. Restaurants are able to mix water and CO2 at the same time. Is there a way to carbonate water without having the shake it?

Rias88 (author)2013-06-11

can i use steel tank and regular CO2 regulator for this system?

waltbosz (author)2011-09-17

I really recommend for anyone that wants to do this Instructable to spend the extra money to get the Carbonator Cap that is mentioned. I started with the tire stem and I found it to have a number of problems. 1. The chuck did not secure onto the valve stem very well which resulted in a lot of wasted CO2. 2. The stem left a bad rubber taste to the water. 3. The carbonator cap and ball lock really do lock together well for a good secure fit which is important while shaking the bottle to mix up the water & CO2.

Other than that, this is a great Instructable. I love being able to make seltzer at home. I was able to get a 20lb CO2 tank, regulator, hoses, and 2 beer taps for $150 off CraigsList.

pcooper2 (author)waltbosz2013-05-15

The Carbonater cap from Liquid Bread, Inc. has apparently been redesigned so that the ball-lock connector can no longer be locked in place.  All one can do is press the connector onto the Carbonater cap for a short burst of CO2, whereupon one is to shake the bottle and repeat the process 5-7 times.

waltbosz (author)waltbosz2011-09-18

Also, I've been thinking of upgrading my setup to use an industrial carbonator like the ones used in restaurant soda fountains. This Instructable shows you how to set one up , or you can visit that author's original web page

snowluck2345 (author)2011-06-30

are standard welding gas cylinders food safe and do they contain food safe co2?

pcooper2 (author)snowluck23452013-05-15

Carbon dioxide gas is carbon dioxide gas. It all comes from the same place, whether it's used for welding, paintball guns or pressurizing a soda system

razldazl15 (author)2011-08-31

I just cam across "BOB’S ENDLESS SELTZER SYSTEM" ; from the picture it looks like a soda syphon connected to a CO2 tank. Has anyone tried some similar setup? This would negate the whole plastic bottle use and maybe even some of the shacking.

pcooper2 (author)razldazl152013-05-15

The Bob's Endless Seltzer System page is a bit skimpy on details. It appears to use a large external stainless steel keg as a water reservoir, pressurized with a regulated CO2 source, to force carbonated water through a cold plate mounted in the refrigerator via some tubing that passes through a hole one must drill into the refrigerator wall. That means the keg needs to be periodically refilled with filtered water and one would need to wait 24-48 hours for gas to diffuse into the water before it's ready to use. Something the size and weight of a stainless steel beer keg filled with water is almost certainly too heavy to pick up and shake to accelerate gas absorption. It's not clear if the siphon bottle needs to be continuously left connected to the hose in the refrigerator, or if one can disconnect it to carry it to the table and elsewhere. The current price for the siphon bottle is about $166, and they say one can assemble the complete system for about $400, depending on where one gets the parts. This Instructables project comes in quite a bit cheaper.

whayden (author)2011-07-02

I've copied this set up and it works pretty well. My questions is why we need to shake the water bottle, whereas the Penguin or Soda Stream just squirts the gas in?

The shaking is a pain in the butt. How do we get our system to work (shake free) like theirs?

pcooper2 (author)whayden2013-05-15

Shaking the bottle vastly increases the area of contact between the gas and the liquid, accelerating the absorption of CO2 into the water.

If you have a secure, leak-free connection to the CO2 supply, all you need to do is pressurize the empty space above the liquid to 60 psi, or so, and the patience to wait 24-48 hours.  The gas will diffuse into the liquid without shaking until a saturated solution is produced.  It's the exact reverse of uncapping a soda and leaving it on your counter at ambient pressure, allowing the CO2 to come out of solution and dissipate in the air.

Spokehedz (author)whayden2011-09-05

Their system wastes gas by injecting it into the water, which mixes the gas and water so that the gas can mix into the water. But, since such a small amount of gas has any chance to mix with the water (it's in the water for milliseconds, then it bubbles out the top) you have to press the button over and over again until enough gas has been mixed into the liquid... which wastes gas.

This system does not waste any gas, because it is a closed system. You shake the bottle to get the gas to mix with the water. That's why you have to shake it. If you don't like shaking it, then by all means buy the more expensive products that do all the hard work for you. I won't, but you can do whatever you want.

I suppose in THEORY that if you had a long tube put from the bottom of the inlet valve that had a very small air bubbler from a aquarium store you COULD get away from not shaking so much, but you would have to inject the gas, open the lid, and inject more gas until you had the right pressure--but you would still be wasting gas and the major point of this entire Instructable is that by doing a little bit of work you can save huge amounts of money

It is also slightly more dangerous (although, not much more dangerous than brewing beer at home which many people do) because there is no valve to release the pressure from the bottle except for the cap. However, this is a minimal risk, as soda bottles have to be tested to some crazy high number like 150PSI without exploding because people leave bottles in the backs of cars all the time.

asteadman (author)2012-09-30

Great Instructable!

I built this exactly as written. Had a couple issues with product numbers, but got enough info to get the right parts.

Had friends over and got to impress their kids buy making "Coke" from scratch. Too much fun!

One question... Once in the glass, the cola loses fizz VERY fast. 5 minutes maybe? Any idea what I'm doing wrong? I do live in Montana. Could elevation be an issue?

Thanks again for posting. Fun weekend project while waiting for my cider to harden. :)

asteadman (author)asteadman2012-09-30

Forgot to mention that I DID use the pre-fab cap from your link. Seems to work well, but it does leak under pressure. Anybody else experience this?

bearing1 (author)2012-09-27

Well Done
Great to see someone making their own seltzer and not using the store bought and chintzy method. I have been doing it for years. Only I have been refilling the old antique bottles from the 20's and 30's. Almost the same method but use a 35 PSI pump to fill the bottles with water, invert them bleed out the air usually it takes to times to fill the bottle. I use chilled water when filling then pressure with the C02. I normally shake while injecting the CO2 for more fizz. This puts to use my old and wonderful bottles. Now they are not just to look at but use on a regular basis. The water will stay "charged" indefinetly as it is sealed and the C02 is the propellant and shoots the water out when pressing the lever. 

breitung1 (author)2012-09-14

Nice instructable. I've basically done the same thing using a lot of your method. The RUBBER based stem, however, degrades in the CO2 atmosphere making the water taste like rubber.

I solved this by moving to METAL based stems - I found bent ones used for motorcycles to help the bottles fit in my fridge. Instead of 2L, I use 3L because the caps are larger and allow the fitting of the metal stem into the cap.

Rather than using a rubber gasket, i was careful to not tear the thin polymer film that's on the underside of every soda bottle. Usually available for about $1/bottle if you buy one with store brand orange soda. Using stainless steel washers and a nut to press the thin film against the underside of the plastic of the cap, i easily got a good seal.

I've been using the same bottles for at least 3 years - it's probably time to switch, but it's a great system.

Also - the metal fittings will allow for the insertion of a tube that can go to near the bottom of the bottle so you don't have to shake!

ameno6 (author)2012-08-06

So, how do the bubbles compare with store-bought fizzy water?

BenTheMakerBot (author)ameno62012-08-06

MUCH more bubbly...(Like at least 1.5 - 2x as carbonated)...Which also means that it lasts longer in the bottle before it goes flat!

timbooth (author)2011-12-19

Regarding the questions below on shaking by us compared with injecting by Soda stream.
I hold my bottles upsidedown whilst bubbling the gas in, thereby causing the gas to pass through the water, this reduces, but does not eliminate the shaking requirement.

Eddie_T (author)2011-12-19

Since we have to shake vigorously to carbonate I wonder how Sodastream accomplishes it without shaking?

llathrop (author)2011-12-09
everything but the co2 tank, in an assembled kit, including carbonator cap for less than the cost of parts everywhere else...and they shipped quick! they also have a kit with the tank.I happened to check these guys for the regulator as they were local to me, but it turns out they moved a few cities away. still the best price I found .

mugsisme (author)2011-11-14

Well, started gathering the supplies, bought a chuck at Pep Boys, opened it up and see that it says to wash your hands after touching it as according to the state of CA, it contains materials known to cause cancer, etc. Are they all like that?
