"Episode106" - This week on "American Inventor" we will focus on three semi-finalists to see how they use the $50,000 they've been given to finalize their invention. Ed Evangelista, one of our expert judges, will mentor three inventors and guide them through the process of working with product designers, packaging companies, marketing executives and product testing. In an ultimate challenge, the inventors will have their new and improved product tested to see if it delivers, and Ed will face the difficult decision of choosing one of his three to move on to the final round, one step closer to winning one million dollars and becoming the next great "American Inventor."
