Lots of people count on helium. From MRI machines and semiconductor manufacturing to pressurizing rockets and detecting leaks, helium is used globally for much more than party balloons. So when there’s a shortage, like right now, the effect is far-reaching. But before the current shortage started, there was already a finite supply on Earth. So, today on Short Wave, we revisit our episode on the history of helium and how the world uses it today.
