I’m feeling better but now i just keep imagining Harry via The Boy Who Ran au collecting a bunch of sharp and possibly lethal perfume bottles that can be used later and just. Fill them with dangerous potions and hide them around Hogwarts.
Instruct people on how to use them as blunt weapons and also grenades. 

Just so when the Carrows are there, the general populations can slam one on the ground and yell “SCATTER!”
