    Today's episode promises to be CRAPPIER than ever - because we're talking about The Martian. That's no judgement on the movie, it's just that the film is ACTUALLY full of poop and poop science. But the question the poop science actually a load of crap? Hold your nose and dive in to discover if it is actually possible for Watney to survive on Mars like the movie portrays.

    Like the theme song? Thanks to CARF!

                  In the book he had pretty big amount earth soil as well. He is a botanist testing plant life on mars.

                    In the book, he also had beans that he could have planted. The book mentions beans and then potato potato potato. And in the movie its just potato potato potato.

                      You know, MatPat's right, this is a complete waste of time to make a movie that can only get a bad credit rating (note to self, my rating, Negative 1000020%).

                                  Did he account for the days during which watney didn't eat potatoes because he spent at least 50 days growing them. I know it doesn't affect the theory at all but still

So unless he used man made lighting i bet the plants would have a hard time creating potatoes of a great size. They have to create sugars from sunlight to store in the tubers.
