Party balloons that, when the contents were inhaled, made your voice sound like Mickey Mouse is what most people remember when they hear the word ‘helium.’ An admittedly risky party trick, making our family and friends laugh at social gatherings was fun nonetheless.
But we shouldn’t be too hard on ourselves. According to Physics Today, party balloons account for 10 per cent of global helium use.
What many of us don’t realize is that there is a lot more to helium than just making funny noises. The element is used in a broad range of important applications: in arc welding, the manufacturing of fibre-optics for internet and computer semiconductors, and in motor vehicle airbags that require quick diffusion.
Helium also helps save lives. Magnetic resonance imaging (MRI) systems, for example, use liquid helium as a refrigerant – cold enough to provide the levels of superconductivity required in MRI scanners. The element is also used in Heliox mixtures for respiratory treatments and nuclear medicine.
