Description / UV Beads and Torch Set
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 our UV beads and Torch Set 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 in the dark 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.
