Check out what happens when someone inhales that stuff:

Is that like the opposite of helium?  ie:  it’s heavier than air, and it makes your voice deeper?

Exactly.  It is a little more than 5 times the density of air so it slows the speed of sound and creates a lower pitch.  Helium is less dense than air and sound travels faster in it.

That is absolutely awesome!!!
Heh, I wonder what my voice would sound like.
