Last year we vowed to curb our bottled water habit but must confess we couldn't resist the occasional bottle of sparkling. Having recently received this Sodastream home carbonation system as a gift from our green guru friend Zem, we are now both absolved and OBSESSED! All you do is fill the glass bottle with tap water, pop in to the machine, push down and lever a few times and voila!: sparkling water that's on par with anything store-bought. (You can even control the bubble size.) Saving the planet and saving money (goodbye pricey imported water!) has never been so easy. 11.06.2009
