These Magic Beads are made from a material that changes colour when exposed to UV light. They're pearly pale when viewed indoors, but change to pastel colours when seen outside in the shade, and bright colours when exposed to strong sunlight. It's like having 3 beads in one, but more importantly, they can be used to help indicate the strength of the sun - so make sure you cover up when they're glowing! They're also ideal for children as a constant reminder of the impact the sun can have. They will change colour backwards and forwards hundreds of times.
