(KMOV) -- Some students are making it pretty easy to find out who vandalized a local school.
They posted a video on YouTube showing their work inside Jerseyville High School, and News 4's Chris Nagus spoke to a student who admits that he did it.
Students said administrators warned them that anyone involved in a senior prank would not walk at graduation. So they waited until the day after.
Parts of the school were covered in toilet paper, a staircase was wrapped in plastic, and removable blue paint was left on trophy cases and glass windows.
It is unclear who videotaped the prank, but the student who admitted to being there says lots of people were there, and while he's not sure how they got in, he's proud of what they did.
Police say the investigation is ongoing.
