well, i have read the article, several times, i still do not see what you are getting at...but theeffect that i was hoping to achieve was like a floating sphere of water, i was surfing the internet, and seen a video of a man with a fish tank that he had filled with some kind of gas...then he proceeded to take a beaker of what i prosumed was water, and slowly poured it into the tank causing it to "float" ifyou will, about mid level of the tank in a sphere! then he took a seringe, filled with air, and inserted it into the sphere of water, and injected it so there was another shpere of air inside of the sphere of water...and then repeated the process two more times.this is something that i have never seen before, but it amazed me, so i decided to try it for myself...do you, or anyone have any knowledge of what i am talking about?
