While reading about your adventure I was chuckling enough that my Mom asked me what was so funny, so I read it to her.  She really got a kick out of it (american slang for amused to the point of loud laughter).

When I was in school, I did not do such things on purpose.  But there is one accidental incident that I am reminded of:

In my highschool science class we had to do on our own with our own resources science and technology experiments and projects, then write a paper reporting on the project, we would also be required to make a presentation to the class.  I undertood the task seriously, but, I did not have the resources available that would be needed for most of the experiment/project/report/presentation, so I improvised with what I did have.

One of my experiment/projects was on the subject of the purity of drinking water, or as it turned out the inpurity of our drinking water.  I wanted to identify the biological, chemical, and particulate  inclusions in the our tap water.

For the particulate inclusions the task was simple, I removed the screen from the kitchen faucet,
turned it on to a marked setting and measure the rate of flow.  After that I placed a funnel below the faucet that lead into a hose so that the water would not be wasted (the hose lead to the garden).  I lined the funnel with filter paper (drip coffee maker filter paper), and turned on the faucet.  After a while I turned it off again once the garden was well watered.  The next day the same thing.  I continued with this process until I had processed 1,000 gallons of water (measured by time based on the premeasured flow rate).  I had to chage filter paper a few times as it began to wear out.  I gathered the particles from the papers into a single clean container. 

For chemical inclusions, I used a washed and boiled out narrow necked glass two liter softdrink bottle.  I filled it part way with tap waer and placed it on the gas stove to slowly boil off.  I kept adding more water as the waster was evaporated away, until I had boiled down another 1,000 gallons of water.  The materials that did not boil away remained in the bottle.  By this I had improvised a reverse still that removed the water (and chemical impurities that had a lower boiling point than water), leaving the rest of the impurities behind.  By the time I was finished I had about a quart of a nice thick yellow mixture left in the bottle.  That if anything looked like urine with the thinckness of pancake syrup.

For the biological inclusions, I was thinking of alge and bacteria.  I left a sample of tap water open out in the yard.  To gather the spores and other material floating on the wind.  I kept replenishing that water as it evaporated, using water that had been rendered safe for aquarium use.  Then using a "toy" micoscope, I identifed the lifeforms in that sample and then identifed the no longer living versions of them in the particulate inclusions from the filter stage of the experiment.

It was not my intention, but during the presentation first one then two then more and more of the students started to look green around the gills (slang for looking ill).  At the time of the presentation I was suffering from a sore throat, so I had a large glass of drinking water that I would take a sip from whenever I found that I was begining to have problems speaking.  As the presentation continued, I noticed that when I reached for the water to drink, most of the students and the teacher would look away (at their desk or shoes or at the ceiling) and not look back at me until they heard me begin to speak again, knowing that I was finished drinking.  Not wanting to cause additional discomfort, I asked the teacher if I could be excused from completing the presentation.  She told me to continue or I would get an "F".  So, I continued.  I did the presentation in the morning session, that afternoon quite a few of the students who were in that class were absent from school.

This was not my only presentation for that class, but it was the only one that most of the students remembered in detail for quite some time.
