Automatically Play YouTube Video in Full Screen Mode

You can change the URL of a YouTube video to force it to automatically open up in full-screen mode. You can use this link for lessons or share with other people. 

Check out the example here: https://www.youtube.com/embed/y2k9O52tEkY 

Steps:

1. Copy this URL: https://www.youtube.com/embed/
2. Click the share button below the YouTube video
3. Copy the Video ID # and paste it after the last forward slash in the above URL (in the video above the ID # is y2k9O52tEkY)
4. Copy the completed URL and use to link or share with others. 

The complete URL will look similar to this (minus a different Video ID #): https://www.youtube.com/embed/y2k9O52tEkY
