Touchstone Lucite NecklaceSoothing, great for relaxation but also great fun! The slightest press or temperature change brings out a rainbow of changing colours on this thermal liquid crystal touchstone necklace. You can also place over the wrist pulse to see your pulse beat! The liquid crystal used here has two formulations so it repeats several of the colours. Since the TouchStone is lens shaped on a perspex backing, viewing it a different angles will also change the colour that you see. The liquid crystal on the bottom of the TouchStone is formulated to swirl and change colours between the temperature of 16°C and 34°C. This is a great toy, relaxation or teaching aid on the science of liquid crystal.
