二硫基丙醇

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).

基 = 其 + 土 : Joan of Arc (ji) has to repair the watchtower (其) In front of the space station (Ø1). The tower needs a new foundation (基), and because it is floating in outer space, Joan of Arc can just add some dirt (土) to its base (基) to create a new foundation.

丙 = 一 + 人 + 冂 : A bronze medal. Brunhilde and Neanderthal Man took part in a scavenger hunt competition and won the third price. They are still holding the map with which they found a flute inside engine as they receive their reward, a bronze medal.
