Can you make a balloon that float in air?

Yes, a helium-filled balloon will float in the air because helium is less dense than the surrounding air. When filled with helium, the balloon experiences a buoyant force that causes it to rise and float.


Why is that a big balloon filled with the helium floats?

Helium is lighter than air. hence helium balloon will float in air.


Can a blimp filled with helium float in the air?

Yes, it can. Just as helium balloon will.


What happen when a balloon is filled with helium?

Why do balloons filled with air not float?

Because air is not as dense as helium filed gallons so they won't float


Will a balloon half filled with air other half helium float?

Yes, a balloon that is half-filled with air and the other half with helium will float because helium is lighter than air. The helium will cause the overall density of the balloon to be lower than the surrounding air, resulting in it floating.


Why will a helium filled balloon will float in air?

A Helium filled baloon floats in air because Helium is lighter than air. Making it rise to the top of it.


Why do balloons float when you put helium in them?

The helium weighs less than air- so when the balloon is filled, it displaces the heavier air, and floats. Just as a bit of wood weighs less than water, and floats on water. In a vacuum, a helium filled balloon would not float (but it may pop)


How does a hot air balloon float if it only filled with air and not helium?

its air deal with it thank you


Why a balloon is filled with helium gas instead of air?

So that the balloons float


What gas are balloons filled with to make them float?

Balloons are usually filled with helium gas to make them float. Helium is lighter than air and provides the necessary lift for the balloon to float.


If you wanted to make a balloon float in the air which gas should you use to fill the balloon?

Helium gas is lighter than air and hence balloons filled with helium will float in air.
