I’m Ken Kuwako, a science educator. Every day is an experiment. Not many science teachers can say they’ve literally been knocked off their feet during class. But real-life science experiments often contain surprises that never make it into the textbooks. Today, I’d like to share a story from one of my own experimental mishaps. It’s […]

I’m Ken Kuwako, a science trainer. Every day is an experiment. Your Eyes Are Lying to You! The Fascinating World of Trick Art “Wait, is that moving?” “It looks 3D — but how?” Have you ever stared at something and simply refused to believe what you were seeing? Today I want to share a mind-bending […]

I’m Ken Kuwako, the Science Trainer. Every day is an experiment. Stretch a balloon with a big “boiiing!” and suddenly your cheek feels warm. Let it relax back to its original shape, and it feels surprisingly cool. All you need is a single balloon. That’s enough to experience the fascinating world of thermodynamics firsthand. I […]

I’m Ken Kuwako, a science trainer. Every day is an experiment. “Why does it come back when you throw it?” Anyone who sees a boomerang for the first time asks that exact question. And it turns out the answer involves not one but several layers of physics — the same science behind airplane wings and […]

I’m Ken Kuwako, a science trainer. Every day is an experiment. There are things we cannot see with our eyes, yet they definitely exist. One of them is “electric current.” Turn on a switch and a light comes on. A motor starts spinning. But what exactly is electric current? After learning circuit diagrams, the next […]
