SUMMARY
The discussion centers on selecting an appropriate gas for a physics experiment that requires easy ionization with basic equipment. Participants suggest using air, which can be ionized at approximately 5kV, provided that a good vacuum pump is utilized to achieve low pressure. However, concerns are raised regarding air's composition, as it contains multiple gases, which may complicate the experiment if purity is required. The consensus indicates that while air is accessible, ensuring a high concentration of a single gas may be necessary for optimal results.
