You can also buy a device to make your own. There are a number of units available, such as this one: http://www.amazon.com/Soda-Club-Jet-Maker-Starter/dp/B003LYBDEO

I have in the past made carbonated water by putting dry ice into distilled water and letting it bubble a while as well.

Thanks Marshall. I checked again this morning and even the ones that say carbonated water have other chemicals as well.

Hi,
I finally got around to going and purchasing the necessary items to make the magnesium bicarbonate water. The only thing is that when I got home I found that the Seagram's club soda I purchased also has potassium phosphate, magnesium sulvate and potasium bicarbonate in it. The directions were specific about having nothing other than CO2 and water but I have been looking and have not been able to find any seltzer or club soda in the stores I have been checking that are only CO2 and water.
Any ideas?
Thanks.

Check out places that have fountain drinks, even restaurants and fast food places. They all have the capability of making carbonated water with those machines, and you might find one that has theirs set up to dispense carbonated water.
