It depends on the damage to the tub itself. There's definitely a point where any normal kid should stop and realize how much damage they are causing, even when lost in the moment. But I mean.. you're watching the entire time. The very second something chips or breaks it definitely registers in your head.
When I was a younger lad, I shot a paintball gun into my closet. It made a cool sound and made a perfect hole. It was... pretty awesome, honestly. So I did it again. And again. Then I did it really rapidly a whole bunch of times. ...yeah...
I also took a pool stick and made holes in the ceiling. My parents must have hated raising me. lmao
Edit: I also lit the kitchen floor on fire with massive amounts of hairspray. And I blew the door halfway off the microwave because I wanted a hard boiled egg. XD
