Whether you're concerned about your impact on the local landfill, or you just like the idea of carbonating your own beverages at home, the Sodastream Source ($130) gives you the bubbles you crave without all the excess plastic bottles. This elegantly-designed device lets you carbonate any drink, from tap water to soft drinks. The included plastic bottle has a metal base and top, is completely reusable, and will last a while — compare that to those disposable bottles you get from the local grocery. LED lights on the machine's face let you accurately gauge your level of carbonation.
Rethink whatever you're using to brew and hold tea, and pick up the beautiful, functional Blomus Sencha Tea Maker & Warmer ($110). The large, easily-filled strainer lets you put in plenty of loose-leaf tea for steeping, and you can serve tea without removing it. A generous 33-ounce capacity lets you brew plenty of tea, whether you're sharing with the office, or drinking all day — and the built-in tea-candle holder keeps it warm. It features a modern design and clear glass and stainless steel construction that looks great and lets you conveniently wash it in the dishwasher.
