Fill a bottle with water and add the jellyfish.  He will float to the top.  When you squeeze the bottle he sinks to the bottom. 

It's just science.  Adding pressure to the bottle increases the force against the jellyfish and trapped air condenses and shrinks, making the jellyfish sink.  Remove the pressure and he floats back to the top.
