The world's smallest violin

You know when they say, when you're whinging about some First-World Problem, that "here's the world's smallest violin playing for you."

And you know how you've wondered how small that might be?

Well, your question has now been answered. 

The answer is it's about the thickness of a human hair. Actually, even smaller than that. And it's made of platinum. 

Well done to the physicists at Loughborough University.
