One characteristic of gas-filled tubes is that after some time the gas inside escapes. The neons simply go out of air. In this context, there may also be changes in color.
There are devices that have no problems for years and are tight for a very long time. In the case of the neons at the “Auwind” daycare center, however, the effect can currently be observed very well.
