Stephen and co -
Some time ago, I had sent Peg and the community a brief curated list of good videos.
See below. Since then, I eagerly add the videos by Thom Cochell:

Subject: Favorite Materials Science Demos
Hello everyone!
I enjoy watching science based youtube videos (probably like a fair portion of those here) but am generally surprised by the lack of quality materials science based demonstrations. Good demonstrations, in any subject, that make a complex topic much clearer are valuable and a treat to experience.
I thought it might be fun to collect a group of quality demonstrations in a thread, so we can all benefit from them. It's also healthy, in my opinion, to admit to ourselves when subjects that we're supposed to know something about are deeply unintuitive.
So, to kick things off, here is my favorite materials science demonstration, the bubble model of crystal structures and dislocations.
Link to Bubble Model
The reason I like this model, and this particular video, so much is that it makes the movement of dislocations easier to visualize. All of my courses on mechanics of materials or crystallography where line defects were a major topic left me with the impression that dislocations are rather disciplined and strict characters. Every encounter I had personally with them were in the form of geometric figures full of angles and rotated coordinate systems, something to be experienced via trigonometry and linear algebra. Seeing the tangle of dislocations in a TEM micrograph did little to help me either, since everything was frozen in place. I feel this video does an excellent job of expressing the chaos of motion that occurs in a plastically deforming metal, in a way that makes both the nature and necessity of dislocations easy to grasp.
I'm curious to see what others share!
