A helium balloon can take you to fulfill your "Flying House" dream!
Helium High purity helium
Many friends have seen the Pixar animated film "Up". In the movie, retired old man Carl uses hundreds of helium balloons to lift his house into the sky, transforming it into a magical "flying house". I believe that friends who have seen this animated film are deeply impressed by this scene, and many people fantasize about using helium balloons to fulfill their dream of flying. However, the idea of "traveling around the world in a flying house" is not just a scene in an animated film. Previously, researchers from the National Geographic Channel were inspired and used helium balloons to complete a real-life version of "the story of a flying house taking off"!

The experimental team was composed of scientists, engineers, hot air balloon pilots, and a group of enthusiastic volunteers. The so-called "Flying House" was not a complete house. In the experiment, the scientists specially customized a very lightweight house. The producer of the experiment said that it was impossible to lift a real house into the air solely using helium balloons, so they designed a new lightweight house. It should be noted that the buoyancy of helium balloons is limited. In previous articles, the editor also introduced how to calculate the buoyancy of helium and how to use the limited buoyancy to lift a house into the air, which is a problem that engineers and scientists need to consider.
Finally, based on rigorous scientific measurements, they utilized oversized helium balloons, each measuring 8 feet in diameter, or 2.4 meters in height, for this experiment. This helium balloon flight experiment is part of a new series planned by the National Geographic Channel. The lightweight house designed measures 4.8*4.8*5.5 cubic meters, large enough to accommodate two professional hot air balloon pilots. After the experiment began, the two professional pilots flew the "Flying House" over the California desert for approximately one hour.
