Element 10, Neon: a pure sample of the famous noble gas in a glass ampule encased within a lucite cube. But how can we know that the glass tube is actually filled with neon gas? If the sample is brought near the 50,000 Volt high frequency electric field of a miniature Tesla coil, the gas will glow with the characteristic orange light from the electron energy transitions specific only to neon. Note that the glow deceases as the sample is moved away from the coil in proportion to the electric fiel
