Always so hard - when ordering online - to tell if something's going to be as neat as it looks/sounds when you see it in person.  As soon as they arrived,  I knew our oldest grandson was going to fall in love with them!  Each one of our three grandsons is special to us in their unique ways... our oldest has somehow combined a love of creativity and the power of an incredibly healthy and active imagination right along with a total level of comfortableness with math and science (at least as of 1st grade!)  We've always strongly connected on the creativity aspect, but I don't know where the math/science prowess came in (... had always heard one section of your brain was usually dominant over the other... overjoyed that both of his, at least for now, seem to be working in unison, since even the words "math" or "science" struck fear in my heart as a child!)
