I LOVE when I learn something new from my students. We are getting ready to do a project in class, and a couple students wanted to know if there was a way to download videos from Youtube to use in their project.
I was about to tell them my old standbys of using a couple different Firefox plugins to do just this, when one of my students piped up with "Oh, you just replace the "www." with "ss" and it downloads it for you."
I was a little skeptical, as I hadn't heard of this before, but lo and behold it's true. For full details on how to do this, check out this video. It's not exactly rocket science, rather than using a plug-in in your browser, it simply redirects you to a third party website that does the trick for you, too.
And then in the next class, I learned about youtube-mp3.org which downloads the audio from a Youtube video, and youtubeinmp4.com which will do both a full video, or just the audio.
I love when I learn things from my students!
