Why are metals so stretchy? (2^13 sub special)AlphaPhoenixI recently ran into the YouTube channel AlphaPhoenix (he's also a member on this subreddit). He has a few nice videos that explain materials concepts somewhat more in-depth than SciShow, but without all the math of a textbook. This one is a good example that explains dislocations in metals.
