So, in the ending scene of titanic, as some might know, Jack sacrifices himself choosing to let Rose float on a door and drowning in the process. However, some people might say that there was enough room for both of them on that door, but even if there was, would the door still be able to float with that extra weigh? I know shit about physics so I am trusting you guys from /sci/ to find that out. Good luck anons!
