It is hard for kids to imagine that everything they see and use was once
invented by someone. From computer games to ball point pens, Teddy
bears to drinking straws, I Wonder Why Zippers Have Teeth
clues kids into the behind-the-scenes people and stories behind many
objects they use every day. The question and answer format is great for
further discussion, the entertaining pictures keep the pages turning. It
will change the way readers think about the things they use, and
hopefully inspire a few to dream up some new ones!
