How Helium Balloons Work HowStuffWorks

There is something incredibly neat about helium balloons! If you buy one at the circus or fair, you can hold its string and it will ride along above you. If you let go of the string, it will fly away until you can't see it anymore. If you hav­e ever wondered why it flies away, then read on.

Helium Flotation - How Helium Balloons Work HowStuffWorks

Helium balloons work by the same law of buoyancy.In this case, the helium balloon that you hold by a string is floating in a "pool" of air (when you stand underwater at the bottom of a swimming pool, you are standing in a "pool of water" maybe 10 feet deep -- when you stand in an open field you are standing at the bottom of a "pool of air" that is many miles deep).

Hot Air - How Helium Balloons Work HowStuffWorks

What about hot air balloons?They work by similar principles. If you heat up a gas it expands. In the case of a hot air balloon, when the gas inside the balloon expands the extra gas is pushed out the bottom of the balloon, meaning that there are fewer atoms inside the balloon, meaning that the air in the balloon is lighter than the air outside the balloon.

How is helium made? HowStuffWorks

If you put helium in a balloon and let go of the balloon, the balloon will rise until it reaches a height of just under 33,000 feet (10 kilometers), at which point it will burst because the atmospheric pressure and the strength of the balloon's skin won't be enough to withstand the pressure of the gas inside it [source: BBC Science Focus]..
