      Well, air weighs a little bit more than 1 kilogram per cubic meter, and those balloons look a little bit smaller than a cubic meter

        What about hydrogen plasma as hot as the surface of the sun, contained in a weightless force field? The 'balloon is simply a decorative wrapper? Remember, it’s the future year 2025!

          Unless there’s force coming from somewhere other than buoyancy, you can’t get better than than 1.29 kg per cubic meter of lift in air at stp.

              You could try to use magnetism or something tho, although that means you’d only be able to walk on specially prepared lakes

                Don’t go down the rabbit hole.

                Next we’ll be trying to explain why they needed a garbage disposal on the Death Star.

                [Two reasons. first, the builder was trying to slow things down so he threw in extraneous stuff. second, there were regulations about ships over a certain tonnage, because no one wants tons of trash falling onto their planet.

                  I was thinking about this a bit yesterday and I think the most feasible way would be to suspend a glass sheet above the lake, and then give people harnesses with magnets on the top that attach to magnets on the other side of the glass sheet. Then just put ball bearings on both sides to reduce friction.

                    Actually, the most logical thing is VR. Give folks full exoskeletons to mimic actual real world conditions and a five sense helmet.

                    Boring to look at from the outside.
