Next time, try a longer fuse.

Since man discovered fire, we’ve loved watching things go “boom.” The first fireworks trace all the way back to the second century B.C., and in the generations since, people around the world have risked life and fingers to create the most dazzling displays possible.

This explosion was intended to be a simple bonfire for a school district. However, something unknown went wrong, and rather than having a cool, casual walk away from the roaring flames, this school resource officer was hit with an enormous kaboom.

Thankfully, no one was injured, but the school says they’re not going to be having bonfires again anytime soon.
