There's no telling what a high school student may have done with a homemade explosive device, but what's clear is that he's in big trouble.
Deputies arrested and charged a 17-year-old from Hudson High School Marchman Technical in Pasco County for having an explosive device inside his home in a backpack.
The teenager never had the bomb at school, but after a bomb squad investigated the device, they determined it was, in fact, capable of doing significant damage.
Luckily, deputies say, the boy's grandmother found the device. She notified the sheriff's office.
The bomb squad found fireworks wrapped around a foam football. They were taped together, and there were bullet casings inside, which could have been shrapnel.
The boy admitted to having the device, but he said he planned on using it in his backyard.
He has been charged with planting a hoax bomb and possession of a destructive device. He was taken to the Pasco County Juvenile Assessment Center.
FOX 13 is not naming him since he is a minor.
