Miracle Beads by Science Museum from £2.65

These beads are white indoors, but turn different colours outside even if the sun is not out. They will change colour over a million times. They contain a special dye - also used in sunglasses - that reacts to ultraviolet light in sunlight. Sunblock creams can stop them colouring! The beads can be threaded to make very cool jewellery that stays coloured for several minutes when you come indoors.
