UNlike this post (Are N2O and CO2 chargers interchangeable for culinary purposes?) I want to know whether you can use the same dispenser for both carbon dioxide and nitrous oxide.
I see that the heads look aesthetically similar but is there any technical difference between downward- and upward-facing spouts?
i.e. what would happen if I put water in a cream dispenser and used a CO2 cartridge instead of cream and a N2O cartridge?
