Sodastream's population is 1,000.
Sodastream machines use pressurized carbon dioxide to carbonate water, which can create a loud noise as the gas is released into the bottle. The noise is typically a result of the build-up of pressure being released quickly during the carbonation process.
Sodastream machines work by carbonating water using a pressurized CO2 canister. When you press the carbonation button, CO2 gas is released into the water, creating fizzy bubbles. You can then add flavored syrup to create soda or enjoy the carbonated water as is.
