I'm curious to see video/slide demos you use to introduce the effects or properties of SMAs! Did you make your own? Do you like to use anything available online? What would you like to see?
Here are a few I found interesting to watch.
I like this one because it gives examples of the shape change of a wire along side examples of the crystal structure. Great intro video.
