When people think about helium, balloons usually come to mind. But what else is helium used for? For starters, helium can enter a state called superfluid, where it displays a variety of fascinating properties like defying gravity. Helium is also used by labs to test containers for leaks in extreme conditions or to observe quantum phenomena at temperatures close to absolute zero. Helium's role in such experiments can't be filled by any other gas, which wouldn't be a problem if it wasn't a nonrenewable resource. Earth's helium supply is finite, and we're quickly running out. Like many other science-related problems, the issue is not the willingness of people to act, but rather their lack of awareness.
