Puzzle Description:
Helium mostly exists in a gas state, and is often used in balloons and dirigibles because it is non-flammable (as an inert gas) and is lighter than air. Aside from Hydrogen, it is the most abundant in the universe. And that means lots and lots of balloons.

Abundant it may be but most of it is in stars and the supply on Earth, squandered as it is in balloons, is running out rapidly. Which will make life difficult for certain branches of physics.#2: Erik Wilke (erwilke) on Jun 16, 2011
Well, if that's the case, then helium's becoming one HOT resource.
