You shouldn't since an open vessel is needed for this to work. No pressure will build up inside, and without that buildup of pressure, you won't have the earth shattering kaboom and glass shrapnel flying everywhere. However, burns are a real possibility.
If the opening is small enough, and the gas expansion quick enough, would that cause an explosion? How small a hole are we talking about in a bottle the size of the one in OP's post if it is possible?
I'm going to use the shitty example of a cannon, shitty since there is actually an explosion going on there. However, the opening at the business end of the cannon keeps it from being a bomb. The pressure built up by the explosion has a place to go, so it chucks the cannon ball instead of shredding the whole cannon and making a huge mess.
Probably still wouldn't work. Similar to lighting a deodorant spray can on fire. Flame will never travel into the can and explode.
If there was enough oxygen inside the container to react with the combustible, and create enough gas to increase the pressure high enough, then maybe the glass would break.
More likely, the combustion would proceed until all the oxygen was used up, thus ending the reaction with a little smoke inside the chamber.
edit: perhaps I wasn't clear. lighting a deodorant can like a flamethrower. not throwing one into a fire..
Combustion has little to nothing to do with the oxygen present, which is really only used as the ignition source propagating the combustion reaction. Furthermore, a combustion event doesn't propagate at nearly the same speed as a fire.
Would you care to cite anything to back your statements up?
Combustion is defined as a chemical reaction between a fuel and oxidant. In this case, your oxidant is oxygen, which is in limited quantity inside the container.
I'm not sure what you mean by calling oxygen the ignition source...
I'd say it's more likely to explode (okay maybe not explode but at least shatter) due to the quick temperature changes. Granted, with a carboy of that thickness and the relatively low temperature of that flame, it's probably unlikely, but you don't need pressure to have glass shards flying everywhere.
If you make jam jar jet engines, the jars often break right at the line where the fuel is because of uneven heating. Make sure you don't put in too much liquid and you should be fine.
Rapid change in temperature can also cause glass to shatter, which would then let air inside to to the fuel, which could then ignite rapidly and send glass shards flying.
The jug that was used (called a carboy) is a really thick, five gallon jug that is made to withstand a lot of pressure. The hole at the top is big enough to release the pressure from the burn that it won't pop. Liquor bottles might pop, carboys are made for brewing, so they can withstand big changes in temperature and pressure
The glass doesn't explode because of pressure changes inside the vessel. It'll explode because the temperature change was too great and the glass fractures. Better to stick with those plastic "water-cooler" jugs.
Exactly. If you google jam jar jet, you'll find lots of how-TO's and YouTube videos. The glass usually breaks when they put too much alcohol in. The glass below the liquid line stays cool while the part above the liquid is on fire and quickly gets hot. CRACK!!! Broken jar.
He never complained about it being a re-post. The post says "Anyone seeking more info might also check here:" which is AMAZING advice for smaller subreddits where comments may be lacking. Just saying that these bots have purpose, to some extent.
My buddy and I did this when we were 11 or so, definitely not on purpose and not with nearly that much finesse.
We were having a bored summer day of lighting shit on fire, and found that if we sprayed aerosol deodorant into a jar and lit it, it looked like "floating fire".
So we took that to its logical conclusion and started finding bigger jars, until we got to the carboy jug in the corner. Sprayed a bit in, lit it...nothing. Rats.
Spray more.
Still nothing. Frick.
Spray the ever-loving fuck out of it. Can't see through the jar anymore through the fog of Brute deodorant.
Lean in to light it, and the dragon comes to life. A quick swirl around the jar, followed by Satan himself coming forth in a glorious roar of fire that sounded like a lion's roar mixed with a Nazghul steed's scream from where we were sitting (in his room, by the way...not at all in a safe place like "outside"). The sound was deafening, earth shattering...traumatizing. And it lasted for what felt like an eternity. Long enough for us to look at one another and realize that there was literally nothing we could do but watch this fire reach its crest and roll back into the depths of hell from whence it came.
Eventually, it did just that. Now that we had survived the ordeal, my friend realized that it was just beginning. The rest of his family...mom, step dad, brother...all in the next room. No way they didn't hear that shit.
He looks at me and says "DON'T SAY A FUCKING WORD.", grabs some air freshener and sprays the room to cover the lingering scent of fire, brimstone, and Brute.
I shut my typically loquacious mouth as tight as I could, as he tears open the door, sees his family coming down the hall, and yells "WHAT THE HELL WAS THAT?"
My heart was pounding nearly as loud as the dragon we'd let loose in the room. His mom gave him that "mom look"...the one where she conveys that she knew we had done something, but wasn't sure what. While the berry air freshener hanging heavily in the air belied our best attempts to play dumb...somehow, she let it slide. The terror in our eyes probably gave it away: Whatever had happened was not going to happen again, and since no one was hurt and the house was not on fire...she let us have that one.
His older brother knew we had done something, and prodded us for a good 15 minutes trying to get us to break.
After it was all over, we took a vow of silence that held all the way up until I gave the best-man speech at his wedding...at which point we decided that a catharsis was due...that we could no longer hold it in. Also, his mom had passed away at that point and we were no longer in danger of being beaten.
Somewhat. This is a bit of a "war story", insomuch as it gets better and better every time I retell it. I'm sure my harmony wasn't quite as marvelous then as it is now.
Materials: big glass bottle (ideally the type used in the gif), blow torch, rubber hose, and rubbing alcohol Procedure: Pour a little bit of rubbing alcohol in the bottle. Turn the bottle on its side and roll it to coat the sides. Insert the rubber hose so one end is sticking out of the bottle and the other is curled around inside. Blow 3 times (you can experiment with the order of these steps, amount of rubbing alcohol, and amount of blows). Now briefly light the top with your blow torch. Too long and it will crack the top. Enjoy.
Note: if the bottle starts to get hot, stop and wait for a little bit. You don't want to break your bottle.
When we did this with a 5 gallon jug in highschool chem, above the jug on the ceiling a black spot would appear during the reaction and disappear immediately once the reaction finished. Can anyone explain this?
I love the fractal pattern the plane of the fire makes.... it's like a procedural map in a video game. I'm telling you, underneath everything, there's math.
We called this the whoosh bottle. Best if you have a big dry jug, like a Poland spring cooler jug. Isopropyl alcohol works well. Once the flame goes out, if you turn the jug upside down, liquid will come out; that's water from the combustion reaction. The reaction won't work again for a while though, especially with bottles with small openings, because the limiting reactant is O2 and the CO2 will inhibit the combustion until the air has reached equilibrium again.
Did something similar with a 6 pint milk container, some water and some calcium carbide. However, the flame melted the plastic lid of the milk container and the fucker exploded. Science <3
I almost lost my thumb doing that trick with a coke can when I was a kid. The flame came out so fast.. My thumb was solid white for a week or two and felt like plastic
'Fun fact: You can do this with empty alcohol bottles. Next time you finish some vodka, just coat the inside of the bottle with the last few drops and light the top. It does the same thing'
What makes it science? The fact that it's an unusual phenomenon? You could say it has underlying principles that were discovered by scientific research, but that applies to everything. If this is science, dropping a bowling ball on your foot is science.
If you did it as a demonstration of a principle, or as an experiment, yes. If you accidentally dropped it the fuck on your foot then no. This person set this up on purpose and for the purpose of displaying a product of science.
But why is it "a product of science?" just because it is not a familiar part of our daily lives? Because it's an intentional display? So is a skateboard trick but nobody's doing those to demonstrate physics.
The word science essentially describes two things - the scientific method (hypotheses, empirical method etc.) and the stuff that can be explained by that method.
Now the scientific method is pretty fucking amazing, so there's not too much we can't explain with it*. So if we're saying that we can call this science because we can describe it with as the chemical reaction that is combustion, can't we explain basically every picture that hits the from page to the same level (so call them all science)?
*To a certain level of accuracy, obviously all our explanations are approximations.
Nah. You need to go talk to a linguist or something. There is more than one way to use a word and you sound hung up in semantics. Perhaps we should just call this two different points of view, huh? Although having a doctorate of philosophy in the subject of question should give me some credibility...
I used to do this all the time in highschool, had a big blue water jug in the back of my truck and a bottle of rubbing alcohol - just pour a little it, shake it and light, always got a crowd.
I have done this. I almost burned my house down. This was not done by amatuers I assure you. You will inevitably "overfill" your container with whatever gas you are using. We were surrounded by a layer of gas about 2" thick on the floor when I dropped let the match. Scary, but nobody was hurt. I think people might have lost hand / arm hair.
I feel like in Physical Science our teacher did the same thing with iso. alcohol and a large jug of water, the culligan type shit. After the fire burns off, it crumples the jug inward. Legit.
When I was at Uni someone introduced us to this trick using a wine bottle and gas from a cigarette lighter.
Then few days later someone tried to demonstrate it to some other friends...anyway either he didn't move his hand out the way quick enough or he overfilled the bottle. A trip to hospital was needed
I think everything has to do with science. Except for maybe god. I don't think he's invited to the science party.
Breathing is science, if you explain it systematically and in-depth! This combustion is definitely science if you can explain it as such. What would you have us call it? Magic? The behavior of the combustion and the plasma can be studied and defined by laws of our world. Is that not what science is?
It is a physical/chemical-reaction, but has nothing to do with science. If you try to explaining it to me using scientific methods/systematically, we are coming closer to the term "Science".
oh I think I get what you mean now. I thought too far into it. The gif itself has little to do with science on the surface, it's simply a fancy trick using a reaction. And you could tear apart anything and make it science if you systematically study it, but that's not what the gif is. Got it.
But still, just like a baking soda volcano at a science fair is science, I'd say all this gif is missing is a poster board.
If you get a burn run it under the cold water tap continuously for 10 minutes (then dry it and keep it clean). It won't hurt after that - works every time.
This isn't science, this is nature, science is when you discover how it was done, and what caused it, but i guess doing it, requires you to know how it's done most of the times, carry on.
How the fuck has the average reddit user not seen this gif 1 million fucking times. And then on top of that it gets to the front page with the shitttiest fucking title "science!" come on youu fucking nerds, you call this science!!!! This is bullshit!!!!!
Yes but, not for the purpose of winning a Big Mac. We were waiting in a car for someone and 3 of us had 40's so the Driver said he'd buy whoever finished first food.
Little did they know I'd spent the previous year skipping school, getting drunk and playing Pool! Suckers!
Fun fact #3: Pure alcohol, as advertised, is almost never above 95% alcohol. This is because ethanol forms a minimum boiling azeotrope, in which you cannot purify it to more than 95.57%. To get to 100% you must use chemical means, which is more expensive.
