This reserve was established by the US Government becaue helium has a number of critical scientific and industrial applications, and it was considered important to ensure that those needs could always be supplied. |
In addition to the scientific uses, helium is also used and sold for more frivolous applications. One of the most well-known is to fill party balloons. Since helium is much lighter than air, balloons filled with it will float. Additionally, because sound propagates differently through helium than through air, inhaling some of the gas will cause a person's voice to sound much higher. The novelty of this phenomenon has long resulted in people inhaling helium from balloons in order to hear their voices change. | In addition to the scientific uses, helium is also used and sold for more frivolous applications.
