Congratulations Isaac! This Inventor/KidPreneur is continuing to take his skills to greater heights and challenging himself by innovating new products for market. His latest creation, The Marble Run! It's so fun! Not only is it a marble race or a maze, but it is one you build yourself and can change over and over again! Inventors are great at making new inventions, whether they are fun or solving a problem. But Isaac is also a KidPreneur because he has learned how to package and sell his inventions as well. In fact, when I first saw his Marble Run, I thought he was ReSelling them! They looked so professional!
