When balloons float they have helium in it. Helium is not air, but a gas. It's lighter than air, which makes it float.
things float in air because of density
Hot air rises and the fire in the hot air balloon wants to go up and float in the air and since it's can't escape the balloon the fire just brings the balloon with it to float in the air
Because it heats the air and of course the hot air will rise above the cold air causing it to float!
The air from your lungs has the same density as the air in our atmosphere. As a result a balloon inflated by a human using their lungs is unable to float.
A cotton ball is thinly attached with lots if air between its fibers. It would be hard to find a liquid it doesn't float on, so the answer is yes to both.
no because the cotton fills with water

No a train does not float in the air, no train does.
If it were, it would float in air. Does it float in air? There's your answer.

The float has air in it.
soda
Only in water. The air from your mouth is the same density as the air in the room- they will not float in air.
Helium is lighter than air. So it will float in air.
Because it has air in it. Air weighs less than water therefore air floats.
