I think you could put sheep on it. Really? Really? Had a great big spike in the middle. You can keep a lamb

kebab on it.

That's so cool. That's extraordinary. I love that. There's a really cool island on Japan, which is called Gunkanjima Island. And what's amazing about this is it was once the most densely populated place on our planet.

It was, it's quite

small. Does that mean there's a lot of people? It's very, very small. A lot of people for a very small island. It's a mixture of the two. So this is the 1900s. And this island, there was Mitsubishi. They looked at it and thought there would be a lot of rich submarine cold deposit underneath. So what they did was they built these buildings on top of the rock. They fitted 6,000 people. There's nothing else you could do but just be in these apartments and then drill downwards to get it. And they were right. There was stuff down there. You'll recognize it, by the way, possibly, if you like popular movies. It's in James Bond's Skyfall. It's where Bond goes to this weird island where it's completely abandoned. And so people go there now. It means

having a bad den. Yes, exactly. Why was it abandoned? Either they mined enough of it or... No, I don't think it was that. Well, I think Japan switched to petrol, tragically. Right. Sorry.

Give it away. Sorry for that, Hannah.

I've got substantial interests in coal. And we really are finding out a lot about you. Wait till you hear the fun to electric diamonds. Anyway, Japan just had a big switchover. Yeah.
