Flask Explosion in Junior-High-School Science Experiment
A triangle flask exploded during a science-class experiment where diluted hydrochloric acid was made to react with zinc to generate hydrogen, at a junior high school. Injures were caused by glass debris flown, five very lightly injured pupils were sent to hospital. Probably hydrogen entered in contact with oxygen because of a wrong experiment procedure, resulting in ignition and explosion.
