You so right. It makes me wonder why when people become chemists that safety is not their number one goal. We chemists play with some pretty nasty stuff that can kill a lot of people quickly under the right circumstances. Every chemist should know deep down inside that they can become very bad people quickly if things get out of hand. Err on the side of caution is my motto.
Unlike universities and colleges, the K-12 have what is known as the "Standards of Learning". When teachers start to go outside those Standards to teach subject material that although maybe exciting but not age nor classroom nor liability appropriate makes me wonder what some people think. When you have potentially dangerous materials like that at age groups that haven't the cognitive abilities to process the dangers involved with using those materials, I begin to wonder why our universities and colleges are not teaching the right perspective about the hazards involved in the work they are about to embark on with the credentials these universities and colleges are granting to those individuals.
Perhaps, the universities and colleges need to have their own "Standards of Learning" to address this seemingly widespread misunderstanding in age appropriate demonstrations.

First and foremost: There are MANY more ways to teach about Newton's third law, about projectile motion, and about combustion that are much safer, much more effective at teaching, more relevant to students' lives, and yes, much more engaging than reckless risks like these.
As for the two video clips: I liked the way the ImaginationStation guys (Toledo) talked about safety first and wore the goggles, but the face shields were never in front of their faces! Furthermore, "it's ok, it went into the streetÉ" REALLY??? My luck, that would have been the moment I would have walked by and gotten hit on the head!
As for the other video: it illustrated a very real and sobering danger: it takes very little expertise and very easily obtainable materials to cause serious injury and property damage in this manner.
All of these incidents speak to a desperate need for oversight of safety in schools: hazard analysis, risk assessment, standard operating procedures, and prior approval of all hands-on investigations.
And if you'll pardon my feeble attempt at irony, these safeguards aren't rocket science either! Seriously, if your local school district doesn't have a safety plan in place, please forward these articles to your school board.

Probably more likely to be either an "alcohol rocket", alcohol rocket launcher" or an "alcohol canon." Use those search terms for a plethora of scary YouTube videos.
Most of the videos use soda bottles and are ignited by a BBQ sparker. Here's a demo of these launchers on a news program. This guy does emphasize safety, but.... https://www.youtube.com/watch?v=HLdRz3C5fQw
This one https://www.youtube.com/watch?v=MRlUFrXGUAA uses a 5-gallon water bottle and a butane lighter. The cap has a small hole in it. Notice the high level of safety precautions in this video. <said with dripping sarcasm>
I'm wondering if this is what was being done at the school?
Again, why do teachers think they have to do explosions????

Whoosh bottle, maybe? From the way the student described it. Could have been any alcohol.

Subject: [DCHAS-L] And ANOTHER likely methanol "accident"
Scant on details, but note the similarity to last week's: alcohol, fire and being done outdoors. Once again, ask yourself why someone would do an "experiment" outdoors as part of a chemistry classÉ.because they realized there was a danger and this was their way to deal with it? That sound you hear is my bloodied forehead pounding on the desk.
A high school student was rushed to the hospital after he was injured in an explosion during a chemistry experiment in New Jersey Wednesday.
The incident happened during an outdoor lab session at Perth Amboy High School during an eighth period chemistry class.
Students told Eyewitness News that experiment involved some type of alcohol. They said the teacher tried to light a match under a gallon-size container, but it didn't work because of the wind. One of the students - the one who was hurt -- then took the matches, tried to light the bottom and the experiment exploded, burning the student.
Several students were nearby when the blast happened, and they said they barely escaped the flame.
"He lit it, and when he lit it he was crouched down," a student said. "So his face was like right there. As soon as he lit it exploded up. It exploded right in his face."
The student who was burned ran from the scene to the nurse's office, and then was flown to the hospital for treatment.

The high school web site contains no information. However, if you'd like to know more about the school and, in particular, how to contact the Principal, see https://www.paps.net/Page/17535 I think Mrs. Rodriguez would benefit from hearing from some DCHAS members today.
