What are these bottles?

My crystal water bottle is made of glass and holds a crystal encased in a pod. The pod does not come into contact with the drinking water to prevent bacteria growth. It is believed that crystals have healing power. There is a science that proves that crystals have energy. This energy is tapped and used to make radios and watches. Some believe that the energy from the crystals promotes wellness and happiness.
