自殺式爆炸

自 = 丶 + 目 : Mnemonic symbol: a hand mirror, which someone uses to look at themselves.

The Eye of Providence (目) is looking at itself (自) in a handheld mirror (自) in the space station's bathroom (Ø4). It think it's indeed looking very good, since Zorro (z) attached a petal (丶) to its eye (目).

杀 = 乂 + 朩 : Sherlock Holmes (sh) is messing around with a sewage pipe sticking out of the floor (朩) in front of the ashram (a1) using pliers (乂). To reduce (杀) the marks he left he is trying to rub them off with an eraser (杀).

式 = 工 + 弋 : I'll use a specific style as mnemonic symbol: 哥特式, gothic.

Sherlock Holmes and the goth are celebrating a Viking festival in the space station's bathroom. They don't have trunks to throw around, so they use a steel beam. They also celebrate by practising archery. In zero gravity it is easy for them to set one world record after the next.

爆 = 暴 + 火 : Beelzebub (b) installed his newest addition to his little hell in the aorta's bathroon (ao4). There is an impressive fire (火) under a deep fat fryer which he will use to punish his clients in the most cruel (暴) way possible by deep-frying (爆) them.

炸 = 乍 + 火 : James II of England (zh) is deep frying (炸) his Mohawk haircut (乍) in the ashram's kitchen (a2), but then suddenly his Mohawk catches fire (火) and he runs into the bathroom.

炸 = 乍 + 火 : As James II of England (zh) runs into the ashram's bathroom (a4) with his Mohawk (乍) on fire (火) the whole building explodes (炸) since there was a lot of methane from the previous user in the bathroom.
