I’m Ken Kuwako, the Science Trainer. Every day is an experiment.<\/strong><\/span><\/p>\n

Have you ever tried that magical candy that changes color right before your eyes? If you’re in Japan, you probably know it as “Neru Neru Nerune.” Many of us remember the excitement of mixing a little powder with water and watching it transform from blue to a vibrant purple. It may look like magic, but it’s actually real chemistry in action. Our science club recently took a closer look at this fascinating reaction, and today I’d like to explore the science behind it with plenty of photos.<\/p>\n

The manufacturer, Kracie<\/a>, explains the science behind the color change in this article. Using their information as a starting point, our science club carried out our own experiments to see the chemistry firsthand.<\/p>\n
