A denser-than-=air gas that you can float objects on.

OO, wikipedia says that this stuff is 5.11 times denser than air, which has a density of 1.2 kg/m^3 at room temperature, and that the aerogels are about a 3 kg/m^3. So put 2 and 2 together... you could float an aerogel on this stuff! It would be the ultimate I-A-B science experiment! :O

oooooh i want some
i would think that it would fly out into open air or something but i guess it stayed since its heavier? :P

technically, with the right shape, size, etc, of boat, you could float a tin foil boat in a vat of CO2, which is one of the densest gasses, and a hell of a lot more common to boot. Or if you`re feeling lucky, methane would be even better, althoug harder to get and more explosive :P.

actually, iouaname, it is like helium, only it makes your voice much deeper.

Yeah I was not amazed by this at all, people are easily amazed, in a few years when knowlege of the gas becomes popular all kinds of tricks will exist.

Think of it as half the power or helium in reverse.

If you could make your cups float with a healium baloon how big would it be? Well it would be half as effective in floating in a vat of this stuff instead of with baloons tied to it.

Also I am sure a cup filled with air is denser than the sulpher hexafloride, so it would sink anyway, you would have to crush the cup up and make it into a bunch of little boat shapes that have very thin walls for it to work, complicated.

Plus, your cups and plates are, of course, denser than air. Therefore, no floaty.

I learned how it deepens your voice off of Daily Planet`s Science In The City. That`s where I learned it from.
No, you couldn`t float your cups or plates next to your chair. Why? Suplphur Hexaflouride is, as said, a heavier than air gas. Therefore it acts as a liquid. This means you would have to fill your whole house, or just a sealed up room, with enough Slphr Hxflrde to float the object at whatever level, just as you would with water. It`s viscosity helps a lot, as it does not act like normal gas, which spreads out rapidly when released, whereas this has denser particles, therefore allowing it to act as a liquid.

Helium and Sulphur Hexaflouride are awesome!

It looks pretty dense alright, the combined mass of the tinfoil and the air inside it would have to be less dense than the gas. Cool!

Uh..."hexafluorid" is nothing. That`s sulfur hexafluoride. Also, I doubt you could actually float on it. People are too dense.

seen the same kind of thing where it was in a balloon and another was filled with regular air the denser one fell like a football :p

Apparently this is Sulphur Hexaflouride.

It is non-toxic, and breathing it would make your voice go deeper. It would only kill you of you didn`t breath oxygen within a suitable time, same as when you breath helium, co2, or nos.

you would only be able to float things on it that are lighter than the gas

Well, I doupt you would die right away, But your Voice would get much deeper.

Afterall you can breath in helium and not die right off.

Lighter then Air Gaz- Voice gets higher.
Heavier then air Gaz - Voice gets deeper.

I wonder what happens if you breathe that stuff in, besides the obvious of dying

Things like that make me giggle.

I want a jar of that Hexafluorid. It will go nicely next to my Areogel.
