Potential Discovery or Invention
A Cathode-Ray Tube (CRT) displays white noise when it is not tuned to any channel. Atmospheric sources of noise are the most ubiquitous, and include electromagnetic signals prompted by cosmic microwave background (CMB) radiation.
Here is a magnified view of the screen of a Sony Trinitron TV set.
Interesting shapes in primary colours show up when dihydrogen monoxide (H2O) is sprayed on the surface of the TV screen because the droplets act as distorted lenses.
Interesting patterns in primary colours show up when a permanent magnet is placed on the TV screen because the electron beams are bent by the magnetic field.
