While it's an understatement to say little is known about this video, one thing is clear -- a group of male students thought it would be a good idea to light a firecracker and throw it down a school stairwell.
The video's title claims the students were expelled after the incident, but no further detail about the punishment or location of the school are given by its uploader, YouTube user Akkadiandude.
This footage harks back to a prank chemical explosion at Craigmont High School in Memphis, Tenn., that resulted in two 18-year-old students being charged with aggravated assault, felony reckless endangerment and possession of a prohibited weapon.
Last year, two Nevada Union High School students faced felony charges of possession of an explosive device on school property, criminal conspiracy, felony vandalism and probation violation, after lacing a toilet with explosives as a senior prank. The explosion shattered the toilet as well as the light fixture above.
"The blast was heard throughout campus," Sheriff's Sgt. Bill Smethers told the Union newspaper at the time. "They are lucky they didn't seriously injure somebody."
