Hellium is less dense then air, so it rises, until it finds it buoyancy level. Whatever upward and downward force that is applied to a object, acts on a object, until it finds it relevant buoyancy level. A example I used is;
Something goes up because you apply a upward force to it. Say take a baseball bat, someone throws a baseball at you, you hit it, hopefully it goes up. That is a upward force that got applied to the baseball. Then through surrounding air pressure, it started losing speed, and as it slows down it starts falling down, as a baseball is more dense then air, and it starts seeking its relative buoyancy level. Once it hits the ground, it has found its relevant buoyancy level, and will lay still there stabel, until a upward or downward force is applied to it once again.
Almost everything is more dense then air, so it will fall down, until it hits the ground. If you look at the periodic table, you will see that Oxygen is the 8 lightest element, Nitrogen the 7th and Carbon the 6th. Anything more dense then this, will seek a lower buoyancy level then 5ft in the air.
Once I use a vacuum cleaner, it sucks it up. All vacuums has to be sealed, by a container, once inside the vacuum, and it is stable, it should seek its buoyancy level, like normal, the most dense object seeks the bottom, of the container.

So what about an object in a vacuum?
Once I use a vacuum cleaner, it sucks it up. All vacuums has to be sealed, by a container, once inside the vacuum, and it is stable, it should seek its buoyancy level, like normal, the most dense object seeks the bottom, of the container.
Do you know what a vacuum is? (Hint. A vacuum cleaner is not an example of one.)
