Ken Kuwako, Science Trainer, here. Every day is an experiment! Normally, the fountain shoots up bright red. But what if it turned purple, green, or blue instead? What would you think? At this year’s school festival, our Science Club put on a variety of science shows. Here, I’d like to share one of them: an […]

When you stop and think about it, it’s a pretty mind-boggling sight. I wanted to experience the whole “how flying works” thing […]

Hi, I’m Ken Kuwako, a science trainer. Every day is an experiment. Did you know that DisneySea is full of hidden parabolas, the same ones you met in math class? The smooth curves that water traces through the air are physics in action. On my last trip to DisneySea, I spotted some beautiful parabolas in […]

Hi, I’m Ken Kuwako, your Science Trainer. Every day is an experiment! Want the big-picture guide to the science of cleaning? Start here: 洗剤の驚異の化学（お掃除の科学） Chlorine-based cleaners (Haiter, Kabikiller, Kitchen Haiter and the like) get their power from sodium hypochlorite, a strong oxidizer that breaks down stain pigments and kills germs. Here’s what they’re good at: […]
