Gas discharge tube filled with low pressure helium. Shows helium's emission spectrum when ionized by a power source such as an Elenco STPS-1 Spectrum Tube Power Supply, a plasma ball, or albeit much fainter, the static charge that can sometimes come off of bubble wrap! When the emission spectrum is viewed thru a spectrometer in a dark room, one can observe the spectral lines characteristic of helium.
