Soda manufacturers can use it to fizz their drinks — something a Swiss customer of Climeworks did a few years ago when there was a carbonation shortage.
Every time you open the bottle carbonation is gradually reduced, so if you like to sip your seltzer you might want to also pick up a few of SodaStream’s ½ liter size to avoid flatness.
SodaStream manufactures its trendy home carbonation machines in Mishor Adumim, an Israeli settlement in the occupied West Bank.
