电压

电 = 乚 + 曰 : Dorothy Gale (di) is looking for a wall plug for her charger (mnemonic symbol for 电) in the anthill's bathroom (an4). She's digging up the whole place with a shovel (乚), but instead of a wall plug she finds a microphone (曰).

压 = 厂 + 丶 + 土 : Maud Younger once heard that if you apply enough pressure, one can make diamonds out of dirt. In front of the ashram, she tries this out: She puts some dirt into a chocolate factory, applies as much pressure as she can, but all that comes out are petal leaves.
