I'm having some difficulty fully understanding buoyancy. If I take a plunger of the type used to unblock drains and then i attach it to the bottom of a swimming pool using its "suction". I think water pressure will be holding it at the bottom but also a bouyancy force will be trying to raise it to the surface of the pool. There seems to be a contradiction, or am i missing something? Can a liquid really provide a downward force as well as an upward force at the same time? Thanks Jason Bloomfield
