Helium is most known for its uses in floating balloons but it has many scientific applications such as preparing NASA rockets testing aircraft in wind tunnels

, cooling MRI magnets, and as a protective gas in the production of semiconductors. Helium is commonly used as a coolant in various scientific equipment due to its low boiling point and ability to maintain extremely low temperatures. In addition, it is used in gas chromatography for its inertness, allowing for accurate analysis of compounds. Helium is also used in nuclear reactors as a heat transfer medium, and in the study of superconductivity and high-energy physics experiments. Overall, helium plays a crucial role in various scientific disciplines and research fields beyond its fun-filled application in filling balloons.
