For example, there are acid attacks becoming popular..
It is so simple, it can be acid in a cup or water bottle, tossed into a person's face.
Imagine if the clubq attack had been using a fire extinguisher full of acid? (Like how just stop oil uses the fire extinguisher to shoot paint, it could easily be a small extinguisher loaded with acid)
These acids are sometimes common household industrial ingredients)
