A less familiar, and more dangerous trick, is to repeat the process using a very dense gasâsulfur hexafluoride. Just like low-density helium displaces the air and creates a high-pitched voice, sulfur hexaflouride also displaces regular air but creates a very low-pitched voice thanks to its high-density.
If you replace the air (Nitrogen-Oxygen mix) with something LESS dense like Helium (1/6th the density of air) then the sounds made by the vocal chords working exactly the same as they did in air, will have a higher apparent pitch because the sonds they make move faster through helium than they do through air.
