Sodastream für 2 € selber befüllen

An dieser Stelle möchte in unserem Sommer-Format “Aus dem Archiv” ein besonders kreatives und ausgefallenes Projekt vorstellen: keyComfort. Um garnicht erst viel Worte zu verlieren, lasse ich einfach das großartige Video unserer Indiegogo Crowdfunding-Kampagne (Web-Archiv 1,2) sprechen: Trotz seiner ansprechenden Ästhetik und professionellen Machart ging die Kampagne weder dort noch auf YouTube viral.
