Very dangerous

Today, while my class english teacher, Miss Feng took us to the ocmputer lab. Someting dangerous happened. While i was surfing the net for the information that i needed to complete my assesment."BOMB" A loud sound had attracted my attention as well as the whole class. One of my classmates had knock onto the fire extinger and smoke started to fill the whole room. Some of us were very lost and dunno what to do. At the next second, people started to run out of the lab. Miss Feng quickly asked us to leave the lab. most of us were choked by the somke that the fire extinger had released. We were very terrified and dunno what to do . Lucky, Miss Feng was very calm and she quickly ask our vice-chairman to report to the office. Then, we let the door to be open so as to let the smoke to "evaporate" into the air. Soon the air outside the room had been polluted. We were coughing and tried to stay away from the scene. Soon, we were told to go back to our classroom. On the way, i can see that all of us were discussing about the incident. I also had join in the fun. Haiz, we sure will be reprimanded for what we had done. Maybe, we had to pay for the loss. Haiz. Saddened. I think i will just leave it to the god and let him decide our fate tomorrow...
