Re: Helium!
Pssshhhhhh, it’s perfectly safe…i think.
That’s because as the helium gas escapes from your lungs, regular air makes its way back in…thus normalising your voice.
If you were to breathe in sulphur hexafluoride, it would take a little longer for your voice to normalise, as it’s a heavier gas, so it hangs around your lungs for a little longer.
And what…:khums:…so are you, admit it!!
