The discussion centers on the visibility of gases and their colors, questioning whether a dense patch of gas can be seen. It highlights that while some gases are colorless, others, like ozone, have distinct colors. The visibility of gases may depend on their concentration and the presence of scattering effects, such as Rayleigh scattering, which can make the atmosphere appear blue. The conversation also touches on the transition of gases to liquids and how that affects their visibility, noting that gases in their pure form are typically not visible unless they are electrically excited. Ultimately, the consensus is that while gases are generally colorless, their visibility can be influenced by various factors, including concentration and environmental conditions.

Well where does it go??

If you immerse a block of chicken wings in a hot oil bath with Oprah around it will vanish.

You call yourself a Canuk? That should be a Rita McNeil joke.

Sorry, Integral; I'll go slap myself now.

That is hilarious, she was exactly who I was going to put but I figured no one would know what the hell I was talking about. Rita definitely takes the fat cake and eats it too, as well as everything else in the bakery.
