ViewPure

Need to show a clip from YouTube to your class but weary of all the ads, comments and other suggested videos - try ViewPure. ViewPure is a cool little web based service for YouTube users to watch YouTube videos in a clean, clutter-free environment. You can paste a Youtube video URL in the box on their homepage and click on “purify” to get the cleaner copy of the video. Not only that, you can also create your own custom URLs and even password protect a Youtube video using ViewPure. This is very useful for teacher to collect classroom resources - now you don't have to worry about where all those links might lead.
