Is there a gas that works opposite of hellium as far changing your voice (deeper sound)?

    Theoretically, Argon would. Under standard temperature and pressure conditions (1 atm pressure and 0 degrees C), the speed of sound in air is 344 m/s. In Argon under the same conditions, it's 319 m/s. Because the sound travels slower in argon, it should deepen the tone of your voice.

    HOWEVER, argon is heavier than air (density of Argon: 1.78 g/L. Air: 1.29 g/L). Because of this, it is very dangerous to inhale. Unlike helium which will "float out" of your lungs, argon can remain in them even after exhaling (remember, it's heavier than air) and you can suffocate.

    Yes. Any gas of high molecular weight would do. However, most high weight non-toxic gases are fairly costly (xenon is an example) so you don't see the experiment performed often.

    sure. you just need a denser gas. idk how healthy that is for you though...
