[h-] Harry Potter is in the [4] bathroom of the [-an] pawn shop where he is trying to 焊 weld some of the leaks in the rusty pipes shut. He takes out an old 干 syringe and casts a spell on it with his wand, which makes a 日 sun appear at the end of it. He then holds that 日 sun-tipped 干 syringe to the holes in the pipe underneath the dirty pawn shop sink, creating a concentrated 火 fire that 焊 welds the holes in the pipes shut.
