Chemical bomb exploded at Atascadero High School
December 15, 2011
The San Luis Obispo County Hazmat team was sent to investigate and clean up after someone detonated a device commonly called a chemical bomb shortly before 7 p.m. on Wednesday at Atascadero High School.
Atascadero police said the explosion of the small chemical bomb did not cause any permanent damage and no one was hurt. However, it is a felony to make and detonate one of these devices.
The bomb maker apparently combined household cleaning supplies in a plastic bottle and sealed it causing a chemical reaction that made the plastic bottle expand and eventually explode, a process frequently taught in high school science classes.
