二等舱

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's living room ((e)ng3), Don Quixote (d) is praying in front of a Buddhist shrine (寺). He brought a bamboo stick (⺮) 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 (等).

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.
