We all like to try to live healthy, and for a lot of us that means drinking vitamin-enriched fluids. Unfortunately, vitamins and other healthful ingredients deteriorate sitting in water. Activate Drinks ($9/4-pack) solve this problem by storing the vitamins and herbs as powder in a chamber inside the cap. When the cap is twisted clockwise, a small plastic blade cuts the seal in the chamber, allowing the ingredients to drop into the water below. Available in four flavors, each with a different nutritional benefit, you're sure to find one that suits your taste and needs. [via]
