It's the volume of the air that makes the difference. If you have the same weight but bigger volume then you have less density than water around you and ultimately you flow up.
I used to ponder about that years ago :-)
Buoyancy depends on density - that is defined as the the ratio between the mass and the volume it contains. The lower the density, the higher the Archimedes buoyancy force given the same liquid. Water for instance.
Compressing air means that you increase the number of molecules in the unit volume, or conversely that you lower the volume of a given mass of air molecules.
The outcome is that the density increases and the buoyancy force, i.e. the Archimedes force gets lower.
And were you right about something like compressed air ?
#28 Nice @$$.
Chicken still thinks he can take 'er down. That's one tough chicken.
I dunno, wassup?

#39 also need one
Hey, they took their empties out with them unlike an Earth Day parade
That one earth day pic you're talking about grom years ago that you and yours keep regurgitating on 8chan has been proven to come from a different event almost immediately after it came out. Pathetic that you have to bring that up in a reaction to something that didn't have anything to do with the environment. Once again, the ones screaming fake news the most are spreading it the most.
#38 you pay for corona
