Transistors, Transistors, Transistors, they do wonders, we’ll teach you how to make an easy and simple project that detects your skin’s “current” if your hands are wet, it’ll light up brighter. Check out how to make the Magic LED light bulb!

I know there are better ways to do this project, you can even go out and buy a magic light bulb from your local magic store for about 3 dollars. But this is definitely a good way to learn a little bit about resistors and transistors, the brighter the LED the harder it’s going to be to turn the light on, so just make sure to find a good balance.
