It was back to school Thursday for students at Ferris High School after two pop bottle bombs in different parts of the campus put a stop to finals week and forced an evacuation Wednesday.
A student confessed to setting off two pop bottles filled with household chemicals which caused a loud explosion and scared students, firefighters said.
"We were all freaking out. It was a weird experience because we have never had something like that happen," said sophomore Alaina Bridge.
No students were hurt, but one janitor did suffer minor burns while trying to clean up the chemicals used in the device.
Thursday was much calmer, the day after fire trucks and police cars filled the parking lot, but students had mixed reactions about being allowed back in the school so soon after the incident.
"It's nice to know that we can come back, but it's kind of scary at the same time … like what could happen," said student Courtney Ford.
The student who admitted to creating and detonating the devices may face criminal charges and financial restitution. It's unknown what punishment he faces from the school district.
