My Brother performed a volcano experiment in a science class. Something went wrong and it exploded burning a bunch of students severely.
There was a Dr. across the street and he immediately began treating them including doing tracheotomies. None died.
An investigation cleared him. It was his teaching assistant who fouled up.
Too much baking soda?
WOW!
A tracheotomy is not something they just do!
Severe neck or mouth injuries...
guessing that this unfortunate student was NOT seriously injured?
Bill Nye always was a dumb ass.
For my 7th grade social studies class project, having studied the volcano near Mexico City, I made a clay volcano on a board, with a small crater at the top. It was surrounded by artificial coal (from my toy train layout) glued to the board.
I had discovered that ground-up sparkler material made a very effective flare, so I brought a very small amount of the stuff in vial, just enough for one demonstration, and the teacher took possession of it. I used a birthday cake candle as an ignitor. In retrospect, I'm amazed that they allowed me to do it, but with the principal in attendance, I set it off. The class loved it! I got an "A" on the project. All of the combustible material was used up in that one demonstration, and it was well tested before I brought it in. Yes, I loved to play with fire as a kid.
But things got a little strange a few months later when a fire broke out in the very same classroom one night. My little volcano was long gone, but there were those who suggested it might have been the cause. I'm sure the teacher backed me up.
The eventual conclusion was arson, but the arsonist was never caught, even though it was generally known who did it.
