MIXED COLOURED SUNNY BEADS
 |
| Neutral to colour |
Our Sunny Beads change colour in sunlight because they are
made from a special ´reversible photo chromic´ material.
This special substance changes its chemical structure when
exposed to ultraviolet light (sunlight), allowing it to absorb a coloured
pigment or dye.
Once out of the sunlight, it becomes neutral again.
A great fun cheap way to show children how Solar Power works
with the sun this summer.
We Have the beads in plain (see picture) or in mixed shapes.
