Soda water can be a refreshing drink on its own, with a squeeze of lemon or mixed with fruit juice or syrup for a fizzy soft drink. While commercial soda water is readily available in almost any grocery store, the cost can be prohibitive if you drink a lot of it. Save some money while avoiding all those empty bottles lying around by making your own fresh soda water. Turn fresh tap water into a fizzy beverage in your own home.
Remove the top from a soda siphon by unscrewing it and lifting it off. Unscrew the CO2 cartridge holder and remove it from the top.
Fill the soda siphon bottle with tap water to the indicated fill line inside the bottle. If your tap water doesn't have a pleasant flavour, filter the water with a filter pitcher before using it.
Replace the top on the soda siphon body. Screw the top on tight so it won't loosen and gas won't escape during use.
Drop a CO2 cartridge into the holder with the smaller end pointing up. Screw the cartridge holder onto the soda siphon top. You will hear a hissing sound when the CO2 begins to enter the canister. This is normal. Continue screwing on the holder until it is flush with the top.
Let the siphon sit for about 15 minutes. Shake the soda siphon for 15 to 20 seconds to mix the CO2 gas with the water, then let it sit for another 5 minutes. Hold the siphon with the spout above a glass. Pull the lever to dispense soda water into your glass.
