It's a gas gas gas!
And it's safer than hydrogen. Hydrogen burns fiercely, ask the Hindenburg crew. That's why we don't use zeppelins anymore.

I know quite a bit about helium as I used to work in a helium factory. However, I didn't like the boss and quit - I refuse to be spoken to in that tone!

No, it's a chemical element as described above. And it's only a gas at higher temperatures. On average in the whole universe, it is liquid or icy solid, because it is usually extremely cold anywhere out there. Helium as a gas is therefore the very very rare exception.

Helium is quite fun, in fact, it's a gas!
