|Is it possible to capture and keep ionized gases or air in a container of some sort? That way they could be sprayed out at any time just like room deodorant. — CW
No, you cannot store charged gases in any simple container. If you try to store a mixture of positively and negatively charge gas particles in a single container, those opposite charges will attract and neutralize one another. And if you try to store only one type of charge in a container, those like charges will repel and push one another to the walls of the container. If the container itself conducts electricity, the charges will escape to the outside of the container and from there into the outside world. And if the container is insulating, the charges will stick to its inside surface and you'll have trouble getting them to leave. Moreover, you'll have trouble putting large numbers of those like-charged gas particles into the container in the first place because the ones that enter first will repel any like charges that follow.
