We conducted the following basic research on plasma. When a mechanical pencil’s core is heated in a microwave oven, yellow plasma is emitted. High resolution spectrometers are expensive and we cannot buy them. In order to confirm the identity of this light, we developed the simple spectroscope that has the resolution to split the D line of a sodium lamp into two lines, and that can obtain a stable and clear image with a digital camera. We used this spectrometer to split the plasma light emitted from the mechanical pencil’s core in a microwave oven. As a result, the light was found to be a strong emission line of sodium. The plasma is generated by exciting the sodium of the ceramic table by the mechanical pencil's core acting as an antenna.
