Up or down or... (Posted on 2005-07-22) Difficulty: 3 of 5
A jar filled partially with water has an object floating in it. The jar is open. Now, if the jar is closed and a vacuum pump is used to pump the air out, what will happen to the floating object? will it rise up more or sink or ...? and why?

boats float

marshmallows float

the water would raise up around the boat (the boat would sink eventually?) while the marshmallow would take up more space on top of the water
