口湖

Mnemonic symbol: 口 shall be represented by a mandarin. Karl Marx (k-) is enjoying a mandarin in the outhouse's living room (ou3).

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. Helga Horse then uses her Confucius beard (胡) to create a loop and let the water, through the surface tension, expand by stretching the loop. She wants to find out how far she can stretch to get a little lake (湖).
