Sodastream

Ditch the bottle runs and carbonate water at home whenever you fancy it. Sodastream machines turn tap water into fizzy drinks in seconds, so you can control exactly how much sparkle you want - gentle bubbles for mixing or proper fizz for drinking straight.

The system's clever CO2 cylinders last for weeks, making dozens of litres before needing a refill. You'll save on plastic waste too, since one reusable bottle replaces hundreds of single-use ones. Add their flavour drops if you're after something sweeter, or keep it plain for a refreshing glass of sparkling water.

Pair your machine with spare bottles and accessories to keep everyone hydrated. Compact designs fit neatly on countertops without taking over your kitchen, and the whole setup requires zero electricity - just press and fizz.
