A mini potion kit built on a real colour-changing reaction, mixed up in your very own test tube. Add butterfly pea powder to water and watch it turn a deep blue. Stir in a lemon powder and it flips to bright pink. Try a seaweed powder instead and it turns a darker blue-green, same potion, two completely different reactions, depending what you add. - A colour-changing reaction, kid-sized, not a trick, real chemistry - Non-toxic ingredients, easy clean-up - Wipes off, hands-on and sensory from start to finish - Mix it again and again, plenty of powder for repeat reactions, not a one-shot potion Top tip: add a shimmer mica for extra sparkle, or fizz powder from Science Discovery to make it bubble over Small potion, big reaction and enough in the tube to do it again the second it's finished. Two kids, same tube, two completely different answers. Both right. Ages 5-7yr
