Five students were injured Wednesday afternoon when a science experiment they were conducting at Toll Middle School exploded, authorities said.
The explosion occurred sometime around 4 p.m. in the school’s cafeteria when a glass bottle they were using as part of the experiment unexpectedly shattered, said Glendale police spokeswoman Tahnee Lightfoot, adding that the experiment was supervised by a teacher.
Kristine Nam, communications director for the Glendale Unified School District, said the students were part of a joint after-school STEM program held by Toll and Hoover high schools. The five students injured in the explosion were all from Hoover, according to Nam.
“Two of them were taken to the hospital for stitches and the other three received very minor scratches so they went home,” she said.
It’s unknown how the explosion will impact the schools’ joint STEM program. The district has not discussed the state or future of the program immediately following the incident, according to Nam.
Glenwood Road, where both schools are located, was briefly closed to traffic as police and fire officials processed the scene.
Lightfoot said an investigation into the explosion is ongoing.
