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

Today, we\u2019re diving into something a little different from static electricity. We\u2019re going to try running a tiny electric current through the human body! You might be wondering, “Wait, through my body?” But with a simple gadget, you can actually see the current flow as it lights up a bulb.<\/p>\n

What is the “Tamesu-kun” Pencil Circuit Tester?<\/h3>\n

One of my favorite tools is called “Tamesu-kun” (meaning “The Little Tester”). It was developed by Mr. Kawakami, a senior of mine from university who now runs an educational materials company. It\u2019s a clever combination of two lithium coin batteries (6V total) and an LED. Since it\u2019s so simple, you can even DIY one at home! If you’d rather buy the official version, you can find it right here<\/a>. This little device opens up a world of experimental possibilities.<\/p>\n

Let\u2019s Create a Human Circuit!<\/h3>\n

Here\u2019s a sudden question for you: Can electricity actually flow through a human?<\/span> And if it does, can you feel it?<\/span> Take a look at this video.<\/p>\n
