Funny story! It reminds me of a time back in my school days when we created a similar concoction to produce hydrogen sulphide in a jar, with a fish tank oxygen pump to disperse it activated remotely from the back of the school hall during assembly. All the teachers sitting on stage were completely distracted halfway through assembly and the third formers at the front of the hall were kept in over lunch time as they were the prime suspects ... until we eventually felt sorry for them and owned up! Got in trouble with my chemistry teacher for creating a potentially toxic gas.
