The principle behind all simple hydraulic devices is that the force is magnified but the pressure stays the same. This is an overgeneralization. Hydraulic devices, like levers, don't always magnify force but can magnify distance moved or velocity instead (think of a water pistol!). Pressure does stay the same though, if we ignore differences due to gravity.
According to Archimedes' principle an object will float when the weight of the displaced liquid is equal to or greater than the weight of the object. True for "equal to" only if it is initially floating. It is neutrally buoyant so it won't rise or sink if initially at middling depth, i.e., not at the top or bottom.
