二氧化碳隔离

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).

氧 = 气 + 羊 : Maud Younger (y) gave the sheep (羊) a balloon (气) inside of the anglepod (ang3), but unfortunately it doesn't float because it is filled with oxygen (氧).

化 = 亻 + 匕 : Helga Horse and Rosa Luxemburg conduct an experiment in the ashram's bathroom. Using a transformer, they melt a ladle.

碳 = 炭 + 石 : Tecumseh (t) further processes the charcoal (炭) he made in the anthill's bathroom (an4) into pure carbon (碳) by crushing the charcoal (炭) into its elements and exerting extreme pressure with a rock (石).

隔 = 阝 + 鬲 : The pope (阝) and Guy Fawkes (g) are heating hotpot from an iron cauldron (鬲) in the elevator's kitchen (e2). Since Guy Fawkes likes to eat hot and spicy but the pope only eats light food, they separated (隔) the hotpot accordingly.

离 = 亠 + 凶 + 禸 : Mnemonic symbol: from 离心机 or 离心分离机, a centrifuge.

离 = 亠 + 凶 + 禸 : Li Qingzhao is about to leave the space station. As a souvenir she put her beret in the space station's centrifuge and got a demon mask out. Angrily she tramples on the demon mask because what she wanted was a nice and modern hat.
