Farah hefted the jug of chemicals and smiled,
"I think this will do," she said.
She set the jug down and rooted through the janitor's closet until she found a pack of matches. She put those in her pocket and unscrewed the lid of the jug. She poured some of the chemical on the floor around the door and on the door its self.
"Everyone clear out. We don't want to get caught in this when it blows," she said. She poured a little trail of the chemical away from the door, put the lid back on, and placed the jug in front of the door. She struck a match. She tossed the flame on to the trail and the fire immediately sprang up. It began to gobble up the chemical, racing for the door.
"Go! Go! Run!" Farah yelled, shooing everyone from the halls.
As they ran through the cubicle area, there was a great fiery whoosh that rushed from the hall as the fire reached it's target. Farah could hear the Words yelping over the crackling of the flames.
"Go! Downstairs!" she yelled.
