the mass increase so does the volume, however the increase in mass is much much less than the increase in mass would be if you were to fill the balloons with air

that doesn't matter

it could be infinitely less

as long as the ratio stays the same...

Which it obviously does if the helium balloons are identical.

Air has a density of about 1.2kg/m^3, however helium at room temperature at standard air pressure is about 0.164kg/m^3 and hydrogen is lower about 0.1kg/m^3

So for each meter cubed of helium you are adding you can lift about 1kg

Are we changing the subject ok then

So when you have about 100 m^3 of helium you should be able to lift a man

Which law is this?

Archimdedes principle

First law

We are still one that?

F = pVg

p = density

V = volume

g = gravity

Can you really lift a man?

@Ivan Pavlovich What's gravity?

all flight is based on lift

No it's not

The thing that facilitates the phenomenon you mentioned

And what would that be please?

most that is

Downwards force, as pointed out in the diagram you posted

Yeah Archimedes didn't use gravity

So I don't know what your point is

See that downwards arrow?

tbh me neither

ignore that

See that upwards arrow?

Yes.

Yeah exactly

So you admit to a downwards force and a normal force?

So as you can see you can modify the direction and rate of acceleration by changing your density

@Ivan Pavlovich force is mass times acceleration is it?

yes?

NET acceleration

What does this have to do with balloons and more importantly gravity
