Basically, helium is very useful for us because it doesn't really do anything; it's totally inert; it doesn't explode like hydrogen, it doesn't corrode like oxygen. That makes it perfect and perfectly safe for all kinds of crazy uses like: making liquid crystal television displays and pressurizing NASA's rockets. Helium is also really good at making stuff, like, freaking cold: it's used in the magnets at the Large Hadron Collider, which we talked about in a previous episode of SciShow and in the MRI machines that doctors use to scan our bodies to...
