My Genius Idea - Episode 8

An invention and ideas competition looking for the next generation of budding inventors. Three young inventors test their ideas to see if they can work. We take to the high seas to see how an idea to protect marine mammals will work. Get the low down on the science behind making electricity in space and hang out at a pig farm to test a remote controlled washing line. Three very different ideas, but judge and expert inventor Tom Lawton can only pick one for the all important final.
