This video appears to be very well done. The video itself does a very good job of giving credit where it is due in terms of the experiments and who made them. In that aspect, it is very good. The thing that I question is whether or not the person who loaded the video had the rights. I am suspicious that they didn't. If they didn't, then, they are copyright violations as they are using more than 10% of the original video.

 

In this segment of the video, there is music that is playing that doesn't have credit given. Now in the credits of the show which are in a different section, there may very well be the credits to the music, so it doesn't infringe copyrights. I would question the validity of the person who uploaded this video though. The video does not appear to belong to them. They state that no copyright infringement intended and that they were only uploading for entertainment purposes. Well entertainment purposes are not covered under fair use, so I believe that this video is actually a copyright violation.
