Actually, they do float. They are lighter than air, so they are supposed to float.
helium is less dense than air. :) so helium will float better than air
If you want the balloons to float, you would probably use helium.
Helium at room temperature is commonly used to inflate balloons due to its low density, making balloons float.
Helium balloons deflate faster because the molecules are smaller and can seep through the smallest of holes. ... Except that this isn't what happens. Try inflating some latex balloons with CO2 (use a chemical reaction with baking soda to generate it) and compare them to helium balloons. It's amazing to see how quickly the CO2 balloons shrivel up. Note: balloons made of mylar or other materials might behave more in line with theory, but CO2 escapes from latex balloons quickly.
Helium is lighter than air, so balloons filled with helium will float. It is also non-flammable and safe to use. Additionally, helium does not react with other chemicals, making it a popular choice for filling balloons.

Helium is lighter than air. so balloons filled with helium will float in air. warming will make them float or rise up faster.
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.

Helium balloons float because helium gas is lighter than the surrounding air. This causes the balloon to be buoyant and rise up in the atmosphere.
Helium balloons float in the air because helium is lighter than the surrounding air. This causes the balloon to be buoyant and rise upwards.
Helium is lighter than air. Hence balloons or blimps filled with helium will float.
Helium to get them to float.

Helium gas is most commonly used to fill balloons to make them float. Helium is lighter than air, which causes the balloon to rise and float.
