 This is Science Friday. I'm Rachel Feltman. The movie Twisters, the long-awaited follow-up to the 1996 movie Twister, drops in theaters today. It's about a tornado scientist who goes back to her home state to try and stop a massive tornado outbreak. On the way, she meets a quirky cast of characters who are mega enthusiastic about tornado science. You thought you could destroy a tornado. We never had a chance.
