I’m Science Trainer Ken Kuwako. Every day is an experiment. Can you imagine placing a tiny toy on your desk and watching it keep its balance all by itself, almost as if it were alive? Even when balanced on the narrow tip of a disposable wooden chopstick, it refuses to fall. It looks like magic—but […]

I’m science trainer Ken Kuwako. Every day is an experiment. Have you ever seen a toy that spins wildly while flying perfectly straight through the air? Why doesn’t something that’s spinning just tumble over? Hidden inside that mysterious motion is an amazing law of physics called the “gyroscopic effect,” the same principle that helps stabilize […]

I’m science trainer Ken Kuwako. Every day is an experiment. Take a look into a swimming pool, and you’ll find something far more exciting than a simple splash. Hidden there is “living physics” — the kind you don’t usually see in textbooks. Reflection, diffraction, interference… these words may sound difficult, but all of these phenomena […]

I’m Kuwako Ken, your science trainer. Every day is an experiment. Just by stacking two pieces of glass together, shimmering rainbow stripes suddenly appear. It feels almost like magic—but this beautiful phenomenon can actually be recreated with everyday materials. All you need are two microscope slide glasses and a strip of transparent tape. In this […]

I’m Ken Kuwako, the Science Trainer. Every day is an experiment. Textbooks tell us that plants use light to make starch. But have you ever stopped and wondered, “Does that really happen?” This time, we carried out an experiment to witness the process with our own eyes. The moment tiny granules inside the leaf suddenly […]
