qqp question1: Suppose we have a really long straw with vacuum in it and closed from both ends. We submerge one end of the straw at the bottom of the ocean, and place the other end in outer space. If we now open both ends of the straw, what will happen to the water in the ocean? question2: What would happen if a closed hollow tube had one end fixed on the earth and the other end raised into space and then both ends were opened?
