The Glacce water bottle is like a regular water bottle, only it's glass instead of a lighter, more practical material, and it has a giant crystal in it, which, the website explains, is to “infuse the water with positive energy. How do crystal water bottles work exactly? Crystal-infused water is water charged by the power of crystal stone and conscious intention, such as in yoga meditations. By placing a crystal stone in a bottle, it gives back its accumulated energy into the water you drink. You may find that the water tastes a little sweeter than regular water. This is because it's absorbing the elements from the crystal it's interacting with. The texture of the water may feel different as well — this is all within the range of normal.
