Library dominoes

What a way to shelf check! I chose this video clip because I'm fascinated by the way these dominoe trails work and then I discovered there were more attached to the clip. So have some fun!
Because YouTube is such a popular site you could add "educational" library clips that people might want to look at. A great way for the Liaison Librarians to run their sessions.
However, as other people have mentioned, you can get hooked on YouTube and it becomes all consuming i.e. a time waster. To be completely negative it seems to me that anyone who has ever made a "cutesie" home video wants to put it on YouTube and some of them aren't that cute.

This is the final week. Thank you Wee Scottish Lassie for your patience and for providing so many interesting things to look at and learn with.
