The chemicals were aluminum foil and hydrochloric acid. The setting was near an outdoors gazebo on school grounds. The context was, in her first version, a "science fair project"; in her second version, she was following instructions given by a friend, not aware it would explode.
A one-day suspension for doing this unsafely seems like about the limit of what's reasonable, and even that is questionable. The focus should be on making sure she knows about the accidental injury possible from this, not punishing her particularly, and encouraging her to continue with her interest in chemistry.
(The number of people I know who went to top-tier schools later who did crazy things much more dangerous than this, such as making fougasse, 5-10 pound black powder pipe bombs, ANFO, etc., is pretty high. They were all white or asian, though, which seems to be what this is about, as well as doing it off school property.)
I was initially a bit more suspicious of the story, assuming she was doing something actually dangerous and then explained it as "a science experiment" when caught, which clearly doesn't seem to be the case.
The prosecution as an adult for felonies... for that there is ABSOLUTELY no excuse. I only hope that these threatened prosecutions do not materialize.
Here's the MSDS data sheet for "The Works" http://www.chemtura.com/msd/external/e/result/report.jsp?P_L...
IIRC, that combination should release H2 and a little heat, but not enough heat to ignite anything. So the bottle basically went "fizz" and "pop".
Some of those plastic bottles can make a loud pop.
AFAICT, it's not a deflagration, it's not a detonation, it's not an "explosion" in any technical sense.
It's a loud noise produced the same way as a popping balloon, it's just at a higher pressure. Plastic bottles are designed to contain the maximum amount of pressure for the amount of plastic they consume, so they don't crack and fizz out like a punctured soda can. They fail all at once.
"IT IS A VIOLATION OF FEDERAL LAW TO USE THIS PRODUCT IN A MANOR INCONSISTANT WITH ITS LABELING."

The "inconsistent with its labeling" part deals with using it as a pesticide.
If you are found guilty (consumers have never been charged under this that I can find a reference to) as a non-commercial user, the penalty for the first time is a warning letter. According to the controlling Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), fines can only be administered if you violate usage another time after receiving a written warning from the EPA.
And none of this has anything whatsoever to do with what she is being charged with. She is not being charged under the Insecticide, Fungicide, and Rodenticide Act.
Those concerned that the FIFRA means you must strictly limit use of EPA controlled pesticide products to specified uses only should consider the fact that since ordinary tissue paper is considered to control the spread of viruses when you have a cold, it is regulated as a pesticide as well under the EPA.
Notice this one allowing an exception - Kleenex will be allowed to remove the ordinarily required "Keep out of reach of children" warning for their EPA regulated pesticide known as Kleenex brand tissue paper.
http://www.epa.gov/pesticides/chem_search/ppls/009402-00010-...
According to the theory that this act strictly controls usage, using Kleenex to clean your glasses is a violation of federal law as that usage is not listed on the label.
Of course we all know that is not the case.
In some other cases, "the penalty for violating labeling rules is death and the punishment may be carried out at the time of offense without benefit of a trial as a natural consequence of the laws of nature and chemistry."
