I'm going to start cranking my music up to max volume.
Why do something like that?
I just want to see if my mom would burst into the room
She probably doesn't like it that loud. You should be more considerate of her.
Well, I want to test my theory so I'm going to do it anyway.
You already know that it's going to bother her so why push it even further to the point of her bursting into your room. That just sounds like it would be a pain for both of you and you could get in trouble. If you really want to listen to your music, loud ask her how loud you can turn it up instead to save you both some trouble.
