Quiet spray

Our hallways have been notoriously noisy (for years, I understand) when students change classrooms. This is my new "weapon of warfare" for the hallways. I will keep it on my desk. When I hear noise in the hallway, I could, if desired, walk out and spray as many students as possible (Don't worry, it won't be in the eyes or anything and it's only aqua). 

Who says being an school leader can't be a little fun?!
