"Activate is a new functional beverage that just launched in Southern California. The drink’s vitamins and herbs are stored as powder in a chamber inside the cap. When you twist the cap clockwise, a small plastic blade cuts the seal in the chamber. Simultaneously, a small armature opens the chamber allowing the ingredients to drop into the water below.
Vitamins and other healthful ingredients deteriorate sitting in water. Storing the ingredients separate inside the cap keeps them fresh until the moment they’re released, for maximum potency."
