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.

beads turn from white to light blue, dark blue, purple, pink, yellow and orange when exposed to sunlight
a great way to teach about UV light, particularly for girls
