My current project is a lot more similar to an entire planet, made entirely out of hay. And someone once told you that maybe somewhere in this planet there might be enough iron molecules to fashion a needle. Or at least part of one. But there might not be. And your only tools are an electron microscope and an arc welder. Plus the planet is on fire, and there are wolves after you.
I promise this makes sense. I'm just not allowed to explain why.
