Superfluid properties

[Edi]

Would a ship float in a superfluid? Would anything float in a superfluid?
I think, that the frictionless behavior of the superfluid would prevent anything from floating, because it just cant "grab" to anything, would be like vacuum, no? Yes, ships float because they displace volume of water with equal volume, but with less mass (contained air), but will that work in a superfluid?

When something falls in a liquid, it feels a punch, because of surface tension, witch wouldn't be without viscosity, right? When something is moving in a liquid, it will slow down without a powersource, because of friction, but not in a superfluid, yes? (it would actually sink to the bottom, or would it?...)

Would a superfluid float in a normal fluid?
That experiment where superfluid dripped out through super-small holes, was there vacuum around that container?

is this a trick question?

Things float in superfluids. Think about energy and forces. Viscosity doesn't enter into calculations of buoyant forces.

Disk pendulum in superfluid helium expierences friction.

By the way friction has nothing with the ability to float (reactive forces for example).
