A cutaway illustration of a coffee maker reveals its inner mechanics in bright amber and gold against a dark charcoal ground, with "Coffee Science" emblazoned in bold orange lettering across the top. Labeled components and flowing liquid streams show the brewing process in technical detail, creating a playful intersection of chemistry, engineering, and the everyday ritual of morning coffee. Water-resistant polyester, hookless and cut extra long to fit any bath, machine washable and made to order. It turns the bathroom wall into the room's best feature.
