Diamond

Transcript:

Sarah: So here's one that, at least in Minecraft is the opposite of squishy. So in Minecraft, if we go down deep underground, or into mine shafts, we'll find diamonds. So we mine the diamond ore, and we will get a diamond out of it. So how does that science measure up? 

Kim: That actually is pretty accurate. So diamonds form deep within our planet's crust, and actually are brought to the surface by something called kimberlites. So these kimberlites are almost like a diamond elevator, if you will, to get diamonds from deep within the crust up to the surface where we can mine them. But carbon, which is the main element of diamonds, is, on the surface, is more likely to form graphite, which is in our pencils, so graphite is very very soft, and that's why, when you rub it on your paper, it actually leaves a mark. That is the the graphite rubbing off onto your paper. 

Sarah: Wow. So one of the new updates is going to change it a little bit, but in Minecraft: Education Edition, diamond tools are the hardest tools that we have in the game, and is that science accurate? 

Kim: Sorry, I was trying to read as well. I'm sorry, Sarah, what was your question, why are the...? 

Sarah: Diamond tools are the hardest ones that we have in the game, and is that accurate? 

Kim: That is accurate. So diamonds are extremely hard. So I mentioned the Moh's hardness scales. So these are number 10, these are the hardest materials on Earth. 

Sarah: Awesome.
