Is this April Fools prank taking is too far?

With the help of another teacher in the school, we plan to pile up all the desks/chairs in our clroom around the teachers desk and duck tape them all together. We also plan to saran wrap it very well. We plan to duck tape the closet shut. We were also going to staple plastic cups together and fill them with water so if you wanted to move them, you would have to pick up 100 at the same time. We plan to do something to the walls, as well, maybe cover them in post-its or aluminum foil. Do you believe this is 'taking' it too far and we might get in trouble?
