Tube is a new tool providing a minimalist view of YouTube. When you go to Tube all you will see is "Tube," a disclaimer, a link to the developer's Twitter account, and a search box. Enter your search terms into the Tube search box and a list of results appears below it without showing any advertising or other sidebar content. When you click one of the videos in the search results it is displayed nearly full-screen on a plain white background.
Applications for Education
If you have ever wanted to show a YouTube video in your classroom but got discouraged by "related" videos or advertisements in the sidebar, Tube is a tool that you should try. Tube won't remove advertisements that are played within the video itself, but it does hide everything else.
A few similar tools that I also like are Quietube, ViewPure, and Watchkin.
