Isn't Cutting a Battery Scary?

I'm more interested in what it can do for me than the actual product itself. It's kind of like if you have a nail and you need it to be like hammered into something I don't care what a hammer really is but if it works that's what I'll use. And then this is the result, right? So ended up learning a lot about chemistry which was very fascinating because there's people who are very fascinated with how electrons move. But even for me I thought it was just like magical. Yeah. Like paint makes sense but to like turn it a different like turn just have a penny. That's what I thought. Long story short. I failed.
