This film was shown widely in classrooms in the late 1960s and early 1970s, usually at the middle-school level, and usually by English or Social Studies teachers. I saw it several times, shown by several teachers. I don't know if it's still in use today in classrooms, but it seems to be largely a forgotten film. It's entertaining all the way through (except the interviews with the scientists does drag a tiny bit, in comparison to the other segments) and inspires you to think and wonder about the processes of creativity, imagination, invention and discovery. In today's world, where it seems like an entire generation has been lost to video games where all you do is go around and kill people, this film may seem like an anachronism. But it should still be shown in classrooms as it may inspire some students to think boldly and create something valuable or memorable during their lifetimes. I would encourage anyone, of any age, who has not seen this to get it and watch it at least once. It's a compact, short film, less than 30 minutes so there is really no excuse for anyone not to watch it.
