In the movie The Martian, after Mark screws the HAB's airlock, he seals the hole using a plastic canvas and some silver-tape. After that, he repressurizes the HAB.
Is this feasible and realistic? Would the canvas and the silver-tape be able to withstand the difference in gas pressure? If so, for how much time? Also, how could he repressurize the HAB with an Earth-like atmosphere if all the air leaked out in the accident?
