汽車

汽 = 气 + 氵 : The Queen of Hearts (qi) conducts an experiment in the space station's bathroom (Ø4). She attached an empty balloon (气) to a water bottle (氵) and uses a lighter to make the water boil. Subsequently the water becomes water vapor (汽) and fills the balloon, enabling the queen to estimate the vapor volume.

车 = 七 + 十 : Charlie Chaplin (ch) is parading in a cabriolet (mnemonic symbol for 车) in front of the elevator (e1), because he wants to establish his new cult. Like all successful leaders, he takes the carrot-and-stick approach: In one hand he's waving with a seven-branched laser sword (七), in the other one he's waving with a cross (十).
