Sunny beads change colour in sunlight because they are made from a special ´reversible photo chromic´ material. This material changes its chemical structure when exposed to ultraviolet light (like sunlight), allowing it to absorb a coloured pigment or dye. Once out of the sunlight, it becomes colourless again.
