I mean a bladder can’t even hold a fifth of a gallon (more like 500ml) so we are already saying it is not possible but assuming there in the future is a human cyborg or a robot the same mass and volume as a human, they would need 60psi and 3.33 gal capacity for two seconds. This info is based on water powered jetpack companies that do this service. So, I did over look one thing: the jetpacks are dual and attached to your legs and they happen over water so not sure the rest of the calculations because I am not certain whether each jetpack has same psi for it to work or it is a combined psi and the water just comes from a hose so there is no capacity but the speed needs to be at least 100gpm.
You may need to double the flow. With the water powered jet packs the water isn’t just being accelerated from a standstill. The water is first flowing up with close to the same speed and is redirected down. So the momentum exchange is twice what it would be if the water were stored in tanks with the flyer.
Yea, I previously just learned that the psi depletes as soon as it leaves the contraption because there is much less pressure, and it is just speed coming out.
That would be a challenge to find out. Because I would look for the material with the minimum durability, not just a metal tank, lol. Like what is the weakest material that can still withstand this type of thing.

what material would a bladder need to be made out of… hrm hold pls
