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.
The fire inside produces hot air, hot air is lighter than clod air so it goes up!
it would for a while but eventually the paper would get wet and heavy and the lantern would sink.
There is a candle at the bottom of the lantern. the candle will then be lighted and hot air rises, which makes the lantern fly. its the same logic as a hot air balloon

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.
Float On Air 010a13d7
The float has air in it.
Only in water. The air from your mouth is the same density as the air in the room- they will not float in air.
Sky lanterns are not legal in Utah or any other state that has adopted the International Fire Code (IFC). While not specifically identifying sky lanterns the definition of a recreational fire would fit what a sky lantern is. The IFC states that all Recreational Fires must be attended by a person at all times until they are completely extinguished.Since a sky lantern is allowed to float away as the air inside the lantern rises in temperature, the flame inside the sky lantern cannot be constantly attended by a person until it is extinguished. The sky lantern is free to float to where ever the air currents take it.The bad part of it is that it may become caught in a tree or on a house or other object and spread it's fire to what ever it gets caught in. This could be a tragic event caused by something that seemed so harmless. Whoever lit the sky lantern would be held responsible for damages caused by their sky lantern.
