湖 = 氵 + 胡 : Helga Horse (hu) is doing an experiment just inside the space station's entrance (Ø2). She lets the water out of a water bottle (氵) and it forms something like a ball very soon.

She wants to find out how far she can stretch to get a little lake (湖).

沼 = 召 + 氵 : James II of England (zh) calls everyone together via intercom (召) to gather in the aorta's living room (ao3). He introduces his latest policy to build a pool (沼) in the aorta. As a symbolic start he opens a bottle of water (氵) and pours it on the floor.
