(MURFREESBORO) -- Several Siegel High School seniors made better use of water over the Memorial Day weekend...washing cars...unlike some students a week ago who used it to soak wrestling mats. The senior prank also resulted in oil being put all over the school's floors and class letting out early one day because of safety hazards. Senior Seth Harrell tells Fox 17 News...

Principal Jason Bridgeman is requiring 8 hours of community service for the nearly 150 students who rearranged school equipment...

Harrell says the original plan only involved arranging chairs and desks on the football field to spell out "2014". Bridgeman originally told the students who did the most damage that they would not be allowed to participate in graduation. He's since said they will be allowed to graduate. They'll have to perform 25 hours of community service before they will get their diplomas.
