Ultraviolet Detection Beads – Pack of 250

Watch science come alive with these fascinating UV-sensitive beads that change colour when exposed to sunlight or ultraviolet (UV) light. Perfect for exploring the effects of solar energy and invisible UV radiation, these beads provide a simple, hands-on demonstration of how sunlight can cause chemical reactions.

Each bead contains a special pigment that reacts to UV rays, transforming from white to vibrant colours such as pink, purple, blue, and yellow when taken outdoors. Once removed from sunlight, the beads return to their original colour, ready to use again and again.
