Our host introduces us to Derek; he’s invented a solar powered air freshener. He’s about to put his freshener to the ultimate stink test; is it any match for the barnyard? We also meet Kelsey and the bird deterrent system she’s devised for her family’s blueberry farm. While our host gives us tips on brainstorming, as he makes his own toy rocket.
