What kind of repercussions or legal troubles would I get for doing this senior prank stunt?

I'm really good at free running and parkour. Google it if you don't know what it is. I'm going to dress up in a spiderman costume with a backpack full web blasters, and then I'm going to crash teacher's clrooms and spray all the students with my web blasters. And what is spiderman w/o acrobatics. I'm going to be doing all types of wall flips and screaming cl 2011. Maybe give shoutouts to all my friends. Front/side flip and handsprings over tables. Gainers and losers off the front stage. Evading security. I hope it won't be a solo act. I'll get like other friends to dress up as characters like villains such as the green goblin, and even batman and the joker. Superman, all other superheroes or just have 10 people dressed up in spiderman costumes lol! And I almost forgot, choreographed fight scenes as well.
