Natrona County Fire crews responded to a science experiment gone wrong this morning at Midwest High School. A small fire from a chemical reaction caused the incident that investigators describe as accidental. One student was treated and released with a chemical burn.

Natrona County Fire Investigator Dave Baker, says they got the call around 9am

"There was smoke in the hallway and in one of the class rooms. Upon interior examination they found an area in the chemistry lab where there as a small fire, but the fire had actually burned itself out."

Baker says there was no structure damage and the fire was isolated to a counter top. He declined to release any more details about the chemicals involved until the investigation is complete, but he did say it was an experiment they'd done many times before without incident.

No explosion or chemical release accompanied the fire.

The incident occurred just after 9am.  First responders isolated the area and classes were sent home for the day.
