A cosmetic used to remove warts, wrinkles and other unattractive facial features forced the evacuation of a Midtown high school Wednesday afternoon, authorities said.
The Tucson Fire Department responded to a call about a strange smelling liquid in one of the school bathrooms at Tucson High Magnet School, 400 N. Second Ave.
The liquid was discovered by teachers working on lesson plans, said Ross Sheard, a chief academic officer for the Tucson Unified School District.
"They found a bottle in the sink and it was foaming up," Sheard said.
The teachers alerted school administrators, who called 911, he said.
Firefighters showed up and evacuated the building, then conducted tests, said Capt. Norm Carlton, a Tucson Fire Department spokesman.

Most of the high school's students had already gone home because of early dismissal. The teachers were participating in professional development training, Sheard said.
Carlton described the liquid as a "weak oxidizing acid."
"It's used for wart removal, wrinkles, things like that," he said.
Once the Fire Department determined the liquid was harmless, people were allowed back into the school.
