I now have a flickr.com account. I've looked around and found an interesting photo at the address:
flickr.com/photos/dunedinpubliclibraries/2647625177. The photo shows kids watching a Hands on Crafts program involving magic tricks,etc.. They have big screens for demonstrating things. Notice that there are two or more people making the presentation. Reminds me of my tea party for the American Girls Book Club.
