The enclosed helium atoms escape through small pores in the latex which are larger than the helium atoms. However, some types of balloons are labelled "helium-grade". These balloons are often thicker and have less porosity. [3] Balloons filled with air usually hold their size and shape much longer, sometimes for up to a week.
Helium also has a very low boiling point (-268.9°C or -452°F), allowing it to remain a gas even in super-cold environments, an important feature because many rocket fuels are stored in that ...

Unlike traditional hot-air balloons , where a single large balloon is equipped with vents enabling altitude control, cluster balloons are multiple, small, readily available and individually ...
