But have you ever stopped to wonder, “How is that exquisite balance achieved?” Believe it or not, there’s a fascinating physics “secret” hidden inside that simple form. Today, […]

I’m Kuwako Ken, your Science Trainer. Every day is an experiment. Sprinkle glittering powder onto a “lonely picture of just a stem,” and instantly, a dandelion bursts into full bloom! Sprinkle powder onto a girl’s empty hand, and poof—a vibrant pom-pom appears! It looks like magic, but of course, there’s a trick. Today, I’m introducing […]
