what i learned was that when you compress the bottle the volume of the tube decreases. let go and the volume goes back to normal and it floats again. the mass of the tube is constant.
To find the Density you have to take mass divided by volume. when you decrease the volume the desity increase. when you increase the volume the density decreases. when you compress the botttle the diver began to decrease its depth. when u let it expand the diver bagan to float back up to the top.
