The UV light detecting beads contain a unique pigment that changes colour when exposed to UV light from the sun or other UV sources. The darker the colour of the beads, the more UV rays they are detecting.

See the magic!

Use the UV beads with our UV Torch (not included) for an engaging way to explore concepts related to light, colour, and more. Children will be fascinated to see how the beads change colour and glow when it's exposed to UV light. Observe and discuss the colour changes, before exposing to the light, when exposed to the light, and after it is exposed to the light.

The science behind

Objects like the UV beads glow because they absorb the invisible UV radiation and emit a light of a different wavelength that is visible to us as luminescence. Objects that continue to emit light after the source is removed are known as phosphorescent.

In full, this product contains:

• 500x UV Beads

Additional Information:

• The UV torch is not included but can be purchased separately
• The UV spectrum emitted by this torch is in the long-wave range which is harmless to our skin and eyes but like all light sources, it is never a good idea to shine the torch directly into people's eyes or our own
