A helium balloon floats because helium gas is lighter than air. By filling a balloon with helium, the balloon also becomes lighter than air. The helium balloon floats for the same reason that objects float on water: objects less dense than water are pushed up by buoyant forces equal to the weight of water displaced by that object. What happens in water also happens in air, and the helium balloon is pushed upwards by a force equal to the weight of air it displaces.

Why do you have to hang onto your helium balloon?
If you let go of your helium balloon it will start to rise because helium is lighter than air.
Why does a helium balloon float up when it is released?
Because helium is lighter than air. So helium balloon will rise up.
What happen when a balloon is filled with helium?
Helium is lighter than air and a balloon filled with helium may rise up.
How does helium behave?
helium behaves by helping to blow thing up nd lainch things
How many pieces of paper can a helium balloon pick up?
it depends on the size of the balloon and the size of the paper

Why does a helium balloon float up when it is released?
Because helium is lighter than air. So helium balloon will rise up.
Why does a balloon filled with helium rise with a balloon filled with an equal volume of average atmospheric air does not?
Helium is less dense than air, which is why the helium-filled balloon floats when you let it go.
Does gravity go inside of a balloon?
No. Air or helium goes inside the balloon.
How do you use balloon in a example?
In a sentence? "He blew up the balloon with a tank of helium."
What makes an helium balloon go up and what makes an helium balloon go down?
a helium balloon is forced upward by buoyancy. a object is forced upward by a force equal to the weight of the fluid it displaces. this also applies to gases. the gas helium is lighter than average atmospheric air, that is that equal volumes of atmospheric air and helium do not weigh the same. This means that the volume displaced by the balloon is heavier than the balloon itself. since the air weighs more it applies more force upwards on the balloon than the balloon applies downwards on the air, therefore it rises. However, a helium balloon will not go down unless a force such as large air resistance (heavy wind etc.) is applied to it. hope this helps.
What is something that can go up quite easily but is harder to bring back down?
A helium balloon with no string.
Why do balloons fly with helium and not with normal human oxygen?
because helium is lighter than air,therefore, when letting go of the balloon it will fly up
How long does a balloon decompose?
When you let go of a balloon the air that is inside of it makes it fly up.It is impossible for it to go up to space.If its without helium then it takes about 6 days.
What goes up when you let go of it?
More than likely a Helium filled balloon. A Hydrogen filled balloon is very flammable and might burst into flames similar to the Hindenburg blimp/dirigible. Helium is not flammable.
