View Pure is a great way to show YouTube clips in class without all the on-screen clutter and dodgy comments. I've written about ViewPure in the past, but the site has had a revamp and is worth another blog post!
Basically you go to ViewPure website, enter the URL of a YouTube video, or do a search, and it then displays the video on a class-friendly page without any of the on-screen clutter.
ViewPure removes all comments, ads, and related videos, allowing videos to be watched without distractions, or more likely, without "inappropriate content".

"Versal is a new way for anyone to create and publish interactive online courses - no coding required. The site provides a simple to use editor to add content, which it then publishes and hosts for you. For free.
Versal uses a system of modules it calls gadgets to easily incorporate videos, surveys, quizzes, diagrams, and other tools to make your course more engaging. Gadgets are mini JavaScript apps that you drag-and-drop into into a course. The basics include text, video and images, but the real magic happens with customizable and interactive simulations, diagrams, timelines, flash cards and more."
