The fancy new camera that David gave me for Christmas takes pictures with such a high resolution that the files are too big for uploading so here's a few more pics from the weekend in the wrong order. FYI, if your camera resolution is too large you can use a program such as Microsoft Digital Image Suite and use the save a copy for web option.
Happy Boy Ligtning Manufactured at The Science Center--Bobbie took the picture for us. There was clapping after the first demonstration and Jack got really upset so we went outside and stomped on the tile in the lobby.
