Glue a wound.
Let’s say you do repairs at your house: one careless move, and you cut your hand, and there are no bandages left. In this situation, you can use super glue. It not only pulls the ends of the wound together but also disinfects it. However, it’s still better to visit a doctor.
so I have a phone, but I'm going to explode it
( and maybe I die, doing it )
instead of calling for help !
