helium
Helium is used in balloons because it is much less dense than air, allowing the balloons to float and is completely nontoxic and nonflammable unlike hydrogen, which is otherwise a superior lifting gas.
The gas commonly used in balloons is helium. It is lighter than air, which causes the balloon to float when it is filled with helium.
Helium is used for inflating balloons and dirigible airships.
Helium
either for balloons, or whip it's.
Helium is a gas used to inflate lighter than air balloons.
Helium is lighter than air (which means it can be used to make stuff float, like balloons) and a noble gas (which means that it won't react with other elements). Both of these qualities make helium very useful.
Helium is used in blimps and balloons. It is the second lightest element to hydrogen, which is not used because it is highly flammable.
Yes, helium weather balloons are commonly used.
Hydrogen, until the Hindenburg,then everyone realized that "Hey, Hydrogen isn't that safe to use!"Hot air balloons, you mean?? Just air that is hot.Actual hand balloons and such? Helium or again, just air. Helium floats better because it is lighter than the surrounding air around it. Helium and air are still used in both.
helium
Lighter than air and not hazardous.
You can use air instead of helium, but it will not rise. The reason helium balloons rise is because helium is lighter than air. I am sure other gases can be used also.
Helium is generally used in helium balloons and blimps. Helium is lighter than air and these items will float in air

helium balloons and make your voice sound weird
