Say a balloon skeleton had negligible mass and a perfectly rigid body, so that it couldn't be deformed in any way. If I vacuumed out all of the air, making the inside a perfect vacuum, would it float? If so, then how much could it pick up relative to its size?

Yep.
It would pick up just as much as the mass of the air displaced
>>
>>7585601
Yes, the concept is called a "vacuum balloon", and it could lift as much weight as the air it displaces. (Minus the weight of the balloon skeleton, of course).
>>
>>7585601
Yes.
About as much as the air displaced by it would weigh, minus the weight of the balloon material. At sea level that's around 1.225 kilograms per cubic meter.

In a vacuum on earth, theres no bouyancy, so even if it weighed the same as a skin flake, it would eventually rest on the bottom.

Vacuum bro, its in a vacuum.

>>7585601
yes but in reality the container mass needed to stop air pressure crushing it will be more than the vacuum inside can lift.

>Vacuum bro, its in a vacuum.

Then maybe you should have stated that when you wrote the OP. OP is, as always, a faggot apparently.

No, if it is in a vacuum it doesn't have lift because it isn't displacing any air.

not OP btw, maybe you should get some sleep.
