二等艙

二 = 一 : Mnemonic symbol: a capacitor, because the two strokes remind me of the symbol in electrical drawings. Albert Einstein (Ø) is experimenting with a capacitor (二) in the space station's bathroom (Ø4). He finds that it's uncomfortable to discharge a capacitor using two flutes (一).

等 = ⺮ + 寺 : Inside of the engine, Don Quixote is praying in front of a Buddhist shrine. He brought a bamboo stick as offer, and he lighted it at the very top. Now he's waiting for the stick to burn down so he can go home. However, the stick is very long: Don Quixote will have to wait for a long time.

舱 = 仓 + 舟 : The King of Chu (c) set up a barn (仓) on top of a yellow submarine (舟) in front of the anglepod (ang1) to add another passenger cabin (舱), but he didn't consider what will happen once the submarine submerges.
