气焊

Mnemonic symbol: a balloon. The Queen of Hearts is disappointed by her balloons. She expected them to float upwards, but in the space station's bathroom, They float randomly in all directions.

焊 = 火 + 旱 : The marmot (旱) is considering to move in with Hamlet (h) and visits him in the anthill's bathroom (an4). To welcome the marmot, Hamlet is welding (焊) a steel sculpture displaying the words "to pee or not to pee!". The sparks caused by the welding set the whole anthill on fire (火) though and so the marmot runs back to its burrow.
