That sharp, painful zap! of static electricity is a common experience, especially on doorknobs in winter. But have you heard of a device called a “Van de Graaff generator”? It can […]

I’m Science Trainer Ken Kuwako. Every day is an experiment! The Daniel Cell is a classic and essential topic for understanding how batteries work. However, I know many teachers struggle with the lengthy preparation and the hassle of disposing of chemical waste. That’s why today, I want to introduce the Hamburger-style Daniel Cell! True to […]
