High voltage and explosive experiments

Some projects did not begin with a formal engineering problem. They began with the same instinct that pulls many young builders toward rockets, coils, engines, loud machines, and other physical systems that feel powerful: the desire to see dramatic phenomena directly, but in a small, controlled, and safe setting. Sparks, flashes, heat, sound, and sudden motion are exciting because they turn invisible fields and stored energy into something the eye can immediately understand.

On the left is a small high-voltage Tesla coil that produces visible electrical arcs. On the right is a controlled high-energy chemistry demonstration (CuO + Al → Cu + Al₂O₃) that produces short, contained flashes and rapid reactions. Other bench projects, such as a foam glider, explored the quieter side of the same curiosity: make a physical effect visible, then tune the setup until the behavior makes intuitive sense.
