I love how everyone is discussing the physics of a cannonball gun DIY setup in a game where magic can instantly teleport people or turn a person into a huge dragon.
I see people make comments like this about shows, movies, etc. and I've never understood this line of thinking. I generally expect things to work the same as they do in real life unless it's explicitly explained otherwise. Not sure if I'm the odd man out in thinking that way or what.
No, you're right IMO. Just because something is different from our world doesn't mean all logical consistency is off the table. This idea is called versimilitude.
you sorta said it but an exception is places like the fae wilds, where you assume physics is only barely present enough to hold your organs together (hopefully)
