Turn off the Lights Chrome Extension

If you show YouTube videos in class this is an extension for you! The Turn Off the Lights Extension allows you to darken the areas outside of the video window in YouTube. This means you can avoid any inappropriate videos and ads that show up and also black out the comments below the video.
It is super easy to use and install. First you will need to download this link at the Google Chrome Extension store for free.  A light bulb icon will appear in your website address bar that looks like this

Now simply click the icon and it will "turn off the lights."  Right-click the icon for options and teh ability to darken the screen even further.  Watch the video below for details on this and more!
