Plasma cutter with pencil lead - Little Shop of Physics

The video tutorial explains how to create a simple plasma cutter using basic materials like alligator clips, tinfoil, lead, and 9-volt batteries. It details the construction process, including setting up the tinfoil and connecting the batteries in series. The science behind the experiment is discussed, highlighting how a small point of contact allows current to flow, creating heat that vaporizes carbon atoms and forms plasma. The final assembly instructions are provided, resulting in a functional plasma cutter.
