SodaStream's popular countertop machines helped lower the cost
of sparkling water by allowing users to make their own. For a
hard-core group of fizzy-water fans, it's still not cheap
enough.
In an effort to save more on each pour, these customers are
hacking into their SodaStream machines by attaching their own
canisters of carbon dioxide, often purchased at welding-supply or
paintball stores. Some are filling gas canisters with dry ice to
create their own fizz. These gambits allow the hackers to avoid the
roughly $15 fee the company charges for refill gas canisters --
which fit into the back of the machine and can carbonate 60 1-liter
bottles of water.
Michael House, 54, who lives outside Bishop, Calif., has kept a
log of the cost savings on his SodaStream since he started hacking
it several years ago. He said a person could invest about $236 in a
10-pound, refillable carbon dioxide tank and connector hose that he
said would yield sparkling water at less than 6 cents a liter.
"The savings are so huge," he said. "The economics here are
obvious."
The practice of SodaStream hacking has become so popular that a
small cottage industry has sprung up to support it. Vendors sell
special adapters to support unofficial carbon dioxide canisters on
the SodaStream, while others offer to refill the SodaStream
canisters in ads on Craigslist and Facebook.
YouTube videos give users pointers on everything from how to
attach a carbon dioxide tank to how to fill canisters with dry ice,
the solid form of carbon dioxide that eventually becomes gas --
protip: don't overfill.
In one popular video, the poster points to a 5-pound aluminum
carbon dioxide tank and says, "You can steal these from landfills
pretty much anywhere." The poster of the video, which has been
viewed over a half-million times, couldn't be reached for comment.
Most hackers interviewed by the Journal recommend using tanks
designed for beverage use, to avoid the risk of unknown
contaminants.
Israel-based SodaStream International Ltd. said it discourages
the hacking and said it isn't responsible for any "bodily harm that
could be caused by misuse."
"Each SodaStream model of sparkling-water makers is designed to
work specifically with our [carbon dioxide] cylinders, and as a
result we advise strongly against using any other methods for
carbonation," a spokeswoman said in a statement.
Luis Badilla, 33, started refilling SodaStream's canisters with
his own carbon dioxide to support his sparkling-water habit of as
many as 10 liters a day -- the equivalent of more than 28 12-ounce
cans.
Mr. Badilla, of Elk Grove, Calif., realized he could save even
more money by refilling other customers' gas canisters as well. He
charges several dollars for each -- still a bargain for the buyer
-- and now fields requests from customers who text him to refill
their canisters at all hours of the day and night.
Mr. Badilla said he uses a scale to make sure he is filling the
bottles properly, and always warns customers to store them at the
right temperature. Mr. Badilla learned that lesson the hard way
when one of his bottles exploded. Luckily, he wasn't injured as the
bottle was in another room of the house.
"It's not extremely dangerous," he said he tells customers. "If
you hear a pop, tell me."
SodaStream "starter packs," which include a machine and one gas
canister good for 60 liters, range from $79.99 to $179.99,
according to the company. A spokeswoman said that a $15 refill on a
60-liter tank will allow customers to make sparkling water for 25
cents a liter.
Deviant Ollam, 42, of Seattle, said he bought a special adapter
that allows him to attach a 20-pound carbon dioxide tank directly
to his SodaStream machine. The contraption sits next to bottles of
wine under a bar in his house.
He said he purchased "food grade" carbon dioxide from his local
gas-supply store, which some SodaStream customers consider to be
safer than the grade of carbon dioxide welders use.
For him, the appeal is less about saving a few cents than using
his wits to get ahead. His family is drinking far more sparkling
water than they did before, just because they can, he said. "Why
drink regular water again when you can have the 'I'm sticking it to
the man' feeling?" Mr. Ollam said.
Sales of sparkling water have skyrocketed across the U.S., with
Americans on track to buy an estimated 821 million gallons of
sparkling brands this year, three times the amount bought in
2008.
SodaStream, which took off in popularity starting in the late
1990s, is widely credited with bringing home sparkling-water
machines to the masses. PepsiCo Inc. said last month that it would
buy the company for $3.2 billion in a deal that hasn't yet closed.
A spokesman for Pepsi declined to comment on customers hacking
SodaStreams.
Chemist Joseph Priestley in 1772 described a technique for
impregnating water with what he called "fixed air," or carbon
dioxide. In earlier years, people drank water that was naturally
sparkling from springs. Mr. Priestley's contraption -- a bladder
connected to a bottle via a leather pipe -- bears a passing
resemblance to the SodaStream.
David Mortman, 46, said twice a year he shells out about $20 to
fill a 20-pound tank with carbon dioxide, and then uses that to
load up the smaller canisters usually used for paintball games that
power his SodaStream.
Mr. Mortman, who lives near Columbus, Ohio, said he buys only
"beverage grade" carbon dioxide from the same tanks that
restaurants use.
Neither "beverage grade" nor "food grade" has a precise meaning,
said Steven Gendel, a scientist with the United States
Pharmacopeial Convention, the nearly 200-year-old organization that
has responsibility for defining the purity specifications of carbon
dioxide used in food.
Mr. Gendel has an easy rule of thumb: SodaStream hackers should
ask for "Food Chemicals Codex, Eleventh Edition, First
Supplement"-grade carbon dioxide.
