Sunny Beads (mixed shapes)

Price: £4.50

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:

  • pack contains approx 100 beads in mixed shapes (candy, shell, star)
  • beads turn from white to purple when exposed to sunlight
  • a great way to teach about UV light, particularly for girls
  • includes ideas for simple experiments
  • beads can be used to make necklaces, bracelets or hair braids
  • Not suitable for under 3's because of small parts
