These CO2 canisters are suitable for use with all major brands of soda syphons. The contents are 100% food grade carbon dioxide.
The soda syphon has a long and proud history can and add a little bit of fizz and sophistication to any cocktail party. The first soda syphon was invented in around 1830 by some adventurous Frenchmen. It was flappers in the 1920s that really made the humble soda syphon into a sophisticated device. Early CO2 soda syphons did on occasion explode – which is why some of the glass ones were encased in a wire cage – so that if they did happen to explode at least nobody would lose an eye.
Now it is easy enough to by pre-carbonated soda water – but that does niot impress in the say was as a swift controlled squirt of seltzer would.

Some CO2 information:
Carbon dioxide is an essential atmospheric gas and is essential to the process of photosynthesis. When dissolved into water then the gas forms carbonic acid. This natural process is what is responsible for the large limestone cave systems in areas such as the Peak District. The acidity of rain – caused as the water falls through the atmospheric carbon dioxide – is entirely natural. It is only when the amounst of CO2 are increased by industrial pollution that the phenomenon known as “acid rain” is detrimental to the environment.
10 CO2 Chargers
These 10 Carbon Dioxide chargers are designed and sold for use with the isi soda syphon. You'll probably just want to get on with making soda water when you open the box – but just in case you're interested in finding out a bit more about their contents, here are some interesting facts about carbon dioxide gas:
CO2 is more dense than air, a gas balloon filled with CO2 will sink.
Carbon dioxide is produced by combustion of anything containing Carbon
CO2 will not support combustion, so is used in fire extinguishers.
CO2 was discovered by a chemist noticing that when things burn they lose mass, this is due to them losing carbon to the atmosphere (as CO2 gas)
Almost all carbon in out bodies comes from atmospheric CO2.
The earth’s atmosphere contains about 0.04% CO2
Levels of CO2 above 0.5% can have adverse health affects
Animals euthanasia can be performed by being exposed to an atmosphere of 30% Carbon Dioxide
Miners used canaries to detect presence of CO2 in mines
Some ocean vents spew out pure liquid CO2
Because it sinks, near volcanoes pockets of CO2 can collect in hollows, this has caused deaths of children playing.
The sea absorbs much of the CO2 that we produce.
Acidification of the sea occurs when it absorbs CO2.
If the sea becomes more acidic it is harder for plankton to form exoskeletons.
Plankton photosynthesis to reduce levels of atmospheric CO2
Humphrey Davy and Joseph Priestly were both involved it the isolation of the gas (and were also both involved in work with Nitrous Oxide)
The Davy Lamp was used by miners to detect CO2, as the gas is more sense than air it sinks, thus a lamp placed near the ground will be extinguished by sinking CO2.
When carbon dioxide dissolved in water it produces carbonic acid
Carbonic acid has a “tangy” taste.
Carbon dioxide can be used in air conditioning units, Coca Cola one of the biggest beneficiaries of tangy carbonated beverages has patented this idea.
In foods then when used as an ingredient CO2 can be listed as E290
Solid CO2 (dry ice) was the earliest was of keeping items frozen during transit.
If you bump up the amount of CO2 present to as little as 1% it can have the effect of doubling the rate by which plants can grow!
When levels of CO2 in the space station were slightly elevated then the astronauts began to get a bit lethargic and report headaches. Some have posited that this will also be an effect of the increased levels of CO2 in the atmosphere (as well as global warming).
