On tonight's Daily Planet we journey onto the set of a film that's using science to bring fantasy to life, and then it's full-steam ahead as we check out a gigantic model train. Plus, on the Allan Nursall Experience Allan gives us the science behind hot rod welding, on Trending we fetch a story about a robotic dog that's getting an upgrade, Ziya checks in with a scientist who says when it comes to sharks smoothness doesn't equal speed, and we've got the answers and winners to this week's Mindbender quiz. All this and so much more on tonight's Daily Planet.
