@HarunDanyal yes they have them but we only take them out for video worthy demonstrations. This is a GOOD use of technology. The moment they text each other it's all over. It reminds me of being able to chew gum in class until some dufus sticks it on the bottom of a table. We can't get rid of tech...we need to use it RIGHT!
@HarunDanyal What's equally crazy is the kid with the camera, able to train that thing on the show, watch the show, and notice the ceiling tile disturbed at the same time! o.0
i'm a 35 year old and i wish my science class was that entertaining or involving as this guys. my was utter non sense with no help from my teacher when i approached her several times. thank goodness these kids have at least a glimpse of what is possible and what is out there with some basic education. just imagine what will happen when they really apply themselves to a topic or subject.
It is an alcohol rocket demo - you can get propanol and isopropanol depending on whether the hydroxyl group is on either the end carbon atoms or centre carbon atom of the 3-carbon spine of the molecule. Propane is a simply an alkane gas. Isopropyl is a shortened name of isopropyl alcohol or propan-2-ol.
NO. Saying isopropyl is not a shortened name. And I know what this stuff is, I'm in an organic chem class, so no it does not refer to isopropanol because they are different things. Isopropyl refers to an isopropyl group like having isopropyl bromide or isopropyl benzene.
I'm more amazed at how some of these kids have smart phones and it looks like they're only in elementary school. I'm 17 and i only have a regular basic phone that can only call, text and, take pictures.
I've found that by adding a small inlet hole for air, you get a longer, more controlled exhaust instead of the pulsejet effect. Did this in my barracks room one time a few years back and nearly knocked out the ceiling tiles lol...
These are dangerous. The bottle can explode. I know of a few instances when students were injured. The rocket bottle is a great experiment, but it should be performed behind a blast shield or in a fume hood. Injuries are the death knell for demos.
very cool demo, but seriously you got some brass balls doing this with the way our government has been going more and more communist. Don't be surprised if your door doesn't get broke down in the middle of the nite and you and your family get shot up by the atf and ice. they don't like smart people.
I don't know how you get away with doing these demonstrations in the classroom. But I'm glad you do. Nothing gets a kid interested in science like watching flames shoot out of nowhere.
If we had more teachers like you, the world would be a much better place.
@rainbowhiker Your wilderness/desert backpacking videos are dangerous to the thousands of impressionable kids on YouTube. Some of them are going to try these things out on their own and eventually, someone will die of exposure, or get bitten by a snake or fall into a ravine. How will you feel then, "Mr. Educator"?
Haven't you learned yet that kids are impressionable? I find this a stupid way to go about teaching. I'm guessing you're going to be sued and discredited, eventually.
I used to do this in my living room with one of the old glass ones. We'd turn off the lights and let it rip. Very impressive and very loud. One day something was different. Either the glass was fatigued or the o2/gas mixture was perfect. Which ever it was, it blew that glass throughout the house, on us, in the walls, everywhere. It was a miracle none of us were killed let alone injured. If I ever saw my kid doing that without proper protection I'd slap him into yesterday.
@MrWallace803 When my parents were not home, i took an old 6 liter glass beaker and me and a bunch of friends sprayed it full of deoderant. We then lit a match and watched the flames. There was a nozzle at the top, so it had a sorta fuse. One time the flame was invisible, i looked down the top, then the flame hit the end of the "fuse". Goodbye eyebrows, eyelids, and my frontal hair.
@MrWallace803 I kind of doubt your kid would do that without proper mentoring. Most kids now are more interested in Facebook cell phones without wondering how their world works. Make me sick.

Dumb thing to be demonstraing to a bunch of kids. For teaching purposes, there are less dreamatic ways to demonstrate your point. Now some of the kids are going to try these things out on their own and eventually, someone will seriously burn themselves. Haven't you learned yet that kids are impressionable? As an educator, I find this a stupid way to go about teaching. I'm guessing you're going to be sued and discredited, eventually.
@rainbowhiker I'm sad that you feel this way. The man in the video is one of the most respected science teachers in the area by peers and students alike. Kids are absolutely impressionable and that is why we do what we do. They must be exposed to the things that will cause them to wonder. Demos grab their attention and give them something to hook their knowledge to. Our test scores prove that we are correct in our methods and you're making some grave assumptions about parental supervision.
@ProjectEpiphany On you tube their are multiple examples of young kids, mostly boys, playing with alcohol, gas, and and other accelerants, thinking it's a fun thing to experiment with. One even shows a child spilling lit alcohol on himself. I would hope this 'respected teacher' shows, as part of his demonstration, the results of burns, with photos of burn victums. What is considered responcible education is going to backfire. It is a sad comment on your thinking and a child will pay the price.
@ProjectEpiphany The far greater risk than kids getting burnt while experimenting (something they will do no matter what, trust me) is that they will never be inspired and never explore nature and science. It is worth a few burns to get kids hooked in science. I burnt myself several times, and got several bad shocks, but I then learned to respect things like that and be careful. The love of science has remained, and greatly enhanced my life.
@ProjectEpiphany I'd have loved to have been in a science class like that. Demonstrations like this instead of just reading the books are awesome and much more likely to result in the kids actually learning something
@cougher989 Another word would be 'disfigurement'. What I'm trying to get through to this person is the danger of a demonstration like this. Kids will want to secretely experiment with it at home or out in a field or at their friends house and eventually someone's going to get burned. Burns are permanent condition and extremely painful. They better be prepared to pay the price for a child to say in a court, 'I learned how to do it at school'.
@rainbowhiker and also you will never get them interested in anything other than sex, video games, drugs, or alcohol (at least this way of using alcohol is better than drinking it, ay?)
@rainbowhiker you suck , stop NERFing the world , an YA ITS IMPRESSIONABLE , thats the point , to get kids interested in science ... you " educators" that stand there an talk at kids with hours of boring facts that make them hate learning is the problem
@Living4fishing You haven't read any of my other comments and if you have, you missed the point I was making entirely. If you can't agree, fine. That's okay. And you're right. I am a terrible speller. Who isn't?
@rainbowhiker Hardly a dumb thing because you also teach them about the Dangers of doing it, this video just show briefly of what he did. As a kid I was doing things like this Looong before 6th grade science, heck by the time I was in 6th grade I had already figured out how to make multiple chemical mixtures... and lost my eyebrow and lots of hand/arm hair.
@SilvaDreams You just restated my point. If you've ever hand anything to do with disfiguring law suits, and the child says, "I learned how to do this in school," they're going to win a huge settlement. But the most tragic part, is the child in burned and they are usually permanent scars and painful injuries. Don't write me anymore please, you guys aren't listening.
So if a child were to some how blame having underage sex on the education system teaching them about it, I suppose they could sue the school as well? Or if they test elasticity of rubber bands in school and later shoot someone's eye out. Or if they see their teacher lighting matches and then set their house on fire? Or if they learned about any reaction of combustion and then recreate it at home and burn themselves?
Nothing can be done if students ignore "Don't try this at home."
@rainbowhiker The fact that it would be the teachers fault, when he clearly says not to try it on your own, is a pathetic example of the failure of our society. That's a parenting issue, or natural selection.
It's a teachers job to teach, and a Parent's job to protect.
@rainbowhiker Yeah, we should all just lock our kids in little boxes so they can't get hurt at all. People are WAY so concerned about kids getting hurt. Without risk, life is nothing but a boring journey of nothingness.
@rainbowhiker what will destroy a child faster than any of this is overprotection... I hope you adjust your attitude before you inevitably breed, or we'll end up with yet another (several) closed-minded fools who thinks litigation and fear are the way to deal with educators
@rainbowhiker there are less dramatic was to demonstrate this stuff but that causes children to become bored and either not pay attention or fall asleep. but when you set shit on fire they will LISTEN and remember it better for say a test
Now all thos kids will be pyromaniacs
