    You did the basic math, with your spherical balloon. What about giant cylinders? Then you could really pack it in.

      Sure. You could do a cylinder of three quarters of a meter across which seems like a reasonable footprint for someone to stand in. That’d only have to be, uh, 325.5 meters tall to have the same volume.

          Your asshole “buddy” constantly throwing sharp objects at your balloon causing you to be wet all the time and laughing as you ask your mom if she can mend your massive cylinder for the 13th time this month

            I’ll just compress more helium and make the balloon metal so its stronger and holds more in a smaller space

              I think holding more helium in a smaller space is the opposite of what you want. The lifting force is equal to the weight of the air being displaced, so you want as little stuff as possible in as big a volume as possible.

              Maybe if you went the other way round and compressed the atmosphere?

              Your buddy has figured out that all they need to do is snip the ropes on your cylinder which will make it fly away and now you gotta ask your mom to buy you a new cylinder until your whole family is broke and homeless

    • You could use spherical balloons with really long, but different length, strings for each person. Of course you’d have to avoid tangling your balloons together while walking around like that and given wind can vary with elevation…
