I had one of these when I was around 6-8 years old. I did a few of the projects, but never spent much time with it until I realized I could hook up each part to an extension cord and when I plugged in the extension cord the part would explode. I spent a lot of time as a kid just making sparks. I loved taking batteries, wire, and a steel file and running the wire up and down the file while it sparked. Totally brainless, yet somehow I still managed to become a EE and an extra-class HAM.
