By combining the shapes of blown glass with different gases and electronic circuits, an endless variety of tube effects are possible.
Filled with a material that gives them bright, sharp colors, Crackle Tubes tubes can be used even under full ambient lighting. They consume very little power, have a long life and can be made with one or more colors in the same tube.
The
photograph below of a crackle tube shows some colored ionized areas which
the human eye may not always see because the color is only emitted at
the end of the brief period that ionization occurs, which the camera happened
to capture in this image.
