国威

国 = 囗 + 玉 : Mnemonic symbol: a nation's flag. Let's say the Chinese flag.

In the observatory's kitchen (o2) Gitta Giraffe (gu) is practising her ballet performance. She got a whole crate (囗) full of jade bracelets (玉) and flags (国) and fixed one flag to each jade bracelet. This makes a perfect combination for throwing the ring with the flag waving behind it and catching the ring again after a few pirouettes.

威 = 女 + 戌 : Mnemonic symbol: James Clerk Maxwell, 马克斯威

Maxwell holds a special lecture in front of the Eiffel Tower, and his students are Bessie Coleman, Willie Walrus and a cute poodle. Maxwell spends a lot of time explaining the inverse power law of electrostatic forces.
