Observe the effect arising from inhaling a much denser gas than air! Due to its density, the frequency with which human vocal cords reverberate (in fact their eigenfrequency) is changed! Do not forget the obligatory handstand afterwards, otherwise you are in DANGER OF SUFFOCATION!!!

  • For some reason, (Couldn't a sense of graphic humor at work here.;-)) I have images of a Chihuahua barking while under the effects of sulfur hexafluoride. LOL

    And no, don't do that to yours or anyone else's puppy, it's just a funny thought, "bark bark," then, "BARRKK BARRRKK." ;-)

  • @geofree1984 he scares me..... me

  • MUAAAAAAAAHHHHHHAAAAAAAA

  • there's no such thing and you can't know what nothing sounds like

  • woaah that was done in my city

  • Sounds like Satan D:

  • well...its safe in small or limited amounts....any gas other than oxygen if inhaled in excess will replace oxygen in the bloodstream and lungs causing oxygen starvation and asphyxiation leading to death.

  • i always wanted some of this :)

  • completely safe it's just like any other inert gas

  • even when adam from mythbusters does it he just breathes in and out
