Sunny Beads (mixed colours)

Price: £4.25

Quantity:

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.

Contents:

approx 100 pony beads

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

beads can be used to make necklaces, bracelets or hair braids
