Many of us have used YouTube videos in the classroom. There are some good videos out there. Many times I have cringed at ads and images not appropriate in the classroom. Quietube.com takes them away! When you go to the website, drag the quietube button to your address bar above. When you pull up the video on Youtube, click on the quietube button on the address bar and all those images go bye bye. There will be an ad or two but they are appropriate retail ads. Easy and safe!
