Online video - Youtube

I do like Youtube although it is yet another time consuming space to play in.  When I was putting together my "Magic" school holiday activity I began using books from the library.  Mostly pretty well laid out and easy to follow.  One trick I just could not understand.  So I looked it up on Youtube and was finally able to master it.  I actually use Youtube quite often for information or instruction.  You should check out the 'quick' way to fold a shirt.  Brilliant.  Then fun for all the family to see who can do it the fastest and neatest.  There are useful ideas on science experiments, craft activities, always cute or interesting baby and animal clips and an endless array of everything you had never even dreamed of.  Can it be used in a library?  Like the video clip I have embedded, it can be useful for spreading knowledge between libraries around the globe.
