In physics classrooms teaching optics or light, the days of using diffraction gratings or electroscopes is gone and these days students and teachers expect to be able to digitally capture and analyze spectra for light sources. Check out the video below showcasing a digital spectrometer used to analyze sources of light such as emission spectra from gases.

Holiday testing is a non-destructive test method applied on protective coatings to detect unacceptable discontinuities that affect the integrity of linings such as pinholes and voids. The test involves checking an electric circuit to see if there is insufficient coating to resist the electrical charge and current flows to complete the circuit. If electrical flow is detected then it indicates the presence of a pinhole or a holiday (discontinuity). Holiday testing is also known as continuity testing.
