- UV Beads Crystal Bracelet Kit
UV Beads Crystal Bracelet Kit
Make pretty crystal bracelets with a twist - they instantly change colour in sunlight! Just like our popular Colour Change UV Beads, these beads remain transparent indoors under regular light bulbs, but under the sun's UV radiation they change a variety of lovely colours. The stronger the UV present, the more pronounced the colour change. Don't just look good, know when to slap on more sunscreen and don the sunnies.

What you get
Chameleon UV Beads Kids Crystal Bracelet Kit. Contains: approx. 30 large crystal UV beads, elastic bracelet thread, metal key ring and instructions.
How does it work
These incredible beads contain an interesting pigment that reacts to UV light, causing molecular shape and colour changes - a light induced chemical reaction called photochromism. Because the reaction is reversible, when the colourful crystal beads are bought indoors away from the sun's UV rays they change back to their original clear transparency. They can change colour and back again thousands of times.
Try putting sunscreen on a bead to see how it effects colour change. How effective is the sunscreen in blocking UV light? How about sunglasses? To what extent do they block UV light?
- The importance of protecting skin/eyes from the sun and its damaging UV radiation.
- The reversible chemical reaction between the pigment inside the beads and UV light that changes the shape of the pigment's molecules and their colour.
- Photochromism: a light-induced reversible change of colour. For example, clear eye glass lenses that transition to dark lenses.
- Experiment by submerging coloured beads in water of different temperatures (lukewarm, hot and ice cold). How does temperature affect the rate at which the beads (or pigment molecules) revert to being colour-free?
The beads change colour within seconds of being exposed to sun or UV light. They do not react to light from light globes and do not, themselves, give off UV radiation. You can even demonstrate the colour changing property of beads indoors using our UV Torch.
