Is it normal to prank my family as revenge?

First you should know I live with a bunch of self centered assholes. We obviously fight a lot everyday, and after the fights I feel very powerless. So as a revenge I prank them. I, for instance, will leave the salt shaker slightly open, so that when they use it all the salt falls all over the food. Or I will put things in someone's closet in a way that when someone opens it a bunch of things fall out and hit them. I leave the dogs poop in places I know people will step on. All the things I do are like that, things I can't be blamed about. I know it's pretty childish but it's the only way I can deal with these people.
