"Gas Collection for Emission Spectra: a favorite demonstration using my set of pure samples of hydrogen, nitrogen, and five noble gasses are subjected to the high-frequency pulsed field of a miniature Tesla coil."
"Each gas has a characteristic breakdown voltage and emission spectrum - note that Nitrogen has the highest breakdown voltage and only glows when very near the coil where the field is most intense whereas Neon and Helium have the lowest breakdown voltage and begin to glow many centimeters away from the coil."
"The color of each gas is due to a mix of the colors emitted from electron energy transitions specific to each element - the basis of spectroscopy. The Krypton tube also exhibits interesting oscillations with this particular Tesla coil."
