Sometimes you can't link to a YouTube video or embed it in your blog because YouTube is blocked. You may need to find the video on another site, like TeacherTube.com or try to download a copy to show locally.

There is a javascript that will help download the video. Just bookmark Download Script and when you are viewing the YouTube video you need, click on the bookmark for additional YouTube download options.

Note that your downloaded video should not be re-posted on the web or you will be violating YouTube terms of use.
