      Absolutely, but the scale of the balloons is a bit off. Nobody would be walking shoulder to shoulder like this. For a normal-ish 170lb/77kg individual your personal balloon would have to be a little under 6.5 meters across assuming it were filled with helium.

      Yes, I did the math.

        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

                  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…

        You could use hydrogen, which is less dense than helium. Then if it catches on fire like the Hindenburg you’d already be in the water.

        Note that you wouldn’t need 77 kg worth of bouyancy from the balloon. The shoes would provide some lift, more if you made them out of some type of foam.

          This I am fairly certain we do not have the technology to achieve. Anything vacuum filled that large would need to have walls so thick so as to completely negate any buoyancy effect. I don’t know of any modern material that would simultaneously be rigid, strong, and light enough.

            Cool sci-fi concept tho

            What other sorts of random issues would be solved by this super material :opens notepad: I mean, everything, right? It would have to be so strong, so light and so economical. You could make actual BattleMechs from it that wouldn’t just sink into every surface they walk on. Shit, Dyson Spheres I guess.

            …so why would we use weird balloon floaties? Isn’t it fun how technology answers it’s own questions?

        Ok but hear me out

        One really BIG balloon with rope systems you could hook on to so multiple people could walk around under the same balloon area.

          Revolutionary. I hear hot air is really good for inflating things. I wonder if you could use some sort of flame thrower to keep the balloon afloat.

      Hot air balloon pilot here: We do, indeed.

      This is a “Cloudhopper”. It’s a hot air balloon with no basket: The pilot straps a propane tank to his back and wears a climbing harness. As you can see, the pilot is, effectively, walking on water with the assistance of the balloon.

      Cloudhoppers are about 20,000 to 35,000 cubic feet, 40-50 feet in diameter. They are about 1/3 to 1/2 the size of most of the balloons you might see at a fair or festival.

    I love that the balloons are far too small. Like they didn’t understand the elements and buoyancy well enough to know the balloons have to be much larger. Not like we have negative mass particles.

      Obviously they were assuming balloons were filled with supervacuum. We have had 100 years and not invented even that.

      Truly we have failed our ancestors.

      Well, I guess they figured it’d take another 100 years to calculate that correctly, so they just winged it for the picture.

    I actually went to that timeline! And its more complex than you think because well yes, there technology is far cooler and more whimsical, abd yes there world is more socialistic, has more free time, better prices and less of a late stage capitalism nightmare…

    But you should just see how many racial slurs those people used just this morning and half of those women cant vote and have polio.

    Also I am pretty sure left-handed people got hunted to extinction for some reason

    Timeline hopping is a mixed bag

        Well I went to a timeline where Reddit managed to organize a nuclear attack against Russia and it backfired HARD, a timeline where we never moved on from the 90s which sounds awesome and it was but the uncriticized ultra-consumption of those times eventually laid waste to the world, a world where JK Rowling succeded at making TERFs the mainstream feminism wave, a timeline where X is the ONLY major website left in the world and its as awful as it sounds, a timeline where being a CIS man was illegal, a timeline where Musk is president, a timeline where pernanently horny sentient sex-robots rule over humanity and a timeline where the soviet union defeated the United States during the cold war so “President” Putin is the most powerful man in the world.

        So yeah…I think there is a problem with my dimensional hopper, it only sends me to “dark” timelines

    Or what an AI in the 2020s thought people in the 1900s would think life would be like in the year 2000

            Debatable. There’s a lot of things in this image that just don’t make sense (ignoring the impossible physics). For example the steering wheel of the water unicycle is connected to nothing. There’s no pedals. The kid behind it is so close it would get clipped by the wheel. Some people are wearing special shoes, some don’t. The balloon shapes and sizes are very inconsistent. Some people in the background don’t have a balloon… Whoever drew this wouldn’t pass art school.
