Water has a higher density than air. Anything that is less dense will float. The tube's covering is not enough to make it sink when filled with air. That is also the reason that oil and water don't mix.

things float because they are less denser then the water. second things do not float, the molecules from the water support the molecules from the thing on the water. that is how something heavy can float. it just has to be boyent meaning it is spread out enough so there is more water molecules to hold it up. if you mean in the air it is the same concept.
Why would inflated balloon float on water?
It's the balloon's volume and mass. If a thing has enough volume to compensate for its mass it will float on water, which also explains why steel ships can float, they have a huge hull. Check out the Yamato, a huge battleship of Japan during WWII.
Should a material have a higher or lower density to float in water?
A material needs a lower density than water to float in water. Ships float in water because their average density is lower than water. The average density includes the steel hull and the air inside the hull.
An object less dense than water will in water?
The "average" density of the object must be less than that of the water displaced.
Why don't mostsubstance float in air if they float in water?
It is waters greater density than air that allows some substances to float on water.

Why does a swimming float float?
Because it has air in it. Air weighs less than water therefore air floats.
Does air float in water?

Why do you tend to float lower in the water when you exhale?
You tend to float lower in the water when you exhale because you are getting rid of air. This air is buoyant and helped you to float higher.
Why do most substances float in air if they flow in water?
I suspect that "flow" is meant to also be "float", but even with that substitution, it just changes the question from nonsensical to counterfactual.Most things that float in water do not float in air.
