WOMAN: So the dry ice [], what that is that's frozen carbon
dioxide and so as the carbon dioxide sublimates and turns
into a gas, that is more dense than air, which is mostly
nitrogen and a little bit of oxygen. And so when I blow
bubbles into it, and I'm blowing out mostly air with just a
little bit of carbon dioxide, it's actually not as dense as
the carbon dioxide in there and so it floats.
I have heard stories about how in the future, maybe
we'll have villages on Venus that'll float in the clouds
in the carbon dioxide that's in the atmosphere there.
