How fitting
Lol, I now see that. XD
I've been wanting a new periodic video for so long, but it was worth the wait
slow mo guys need to do this
zoomksa1212 1,000,000 FPS?^^
0:01 Neil: "Yep."
Oh my God, he _did speak_.
So basically your repeating an experiment you did before, but Neal is doing it so it's far more hardcore

Oh no I'll have to commit Seppuku with my computer keyboard.
Another weeabo bites the dust

No Seppuku, the act of a Japanese worrier stabbing themselves to save honor.
Ieuan Hunt you needed an exclamation mark after *Oh no!*
Always good to see you on camera Brady! Even if it is from back in the days when my chemistry teacher was the one to show us your videos... How to create large amounts of fire in a classroom. Superb as always.
You should contact the slow mo guys to try this with their 170k fps camera!
I spent all yesterday wondering when I'd get another video to watch from this channel. Thank you for obliging.
You could try it with acetylene and oxygen. The lecturer in a welder course did that to show us how dangerous that mixture is. Unfortunately some coworkers tried to do that wirhout some ear protection at work, when I was in an apprientice ship.
Brilliant as always
This is also a great explanation of why gas leaks can be so dangerous. When gas leaks and collects in your house, if it reaches that mixture point, it would take the tiniest of sparks for a massive explosion to do a bit more than a "bang"
Ask a better high speed camera from Destin or SloMoGuys and repeat the experiment. I think you need 100000FPS for this to capture - similar to SED Rupert's drop experiment. Resolution will suffer but people will appreciate your efforts :D :)
A very well done experiment! I really enjoy watching the video. Can't wait to start experimenting in Uni soon. This makes my day and the chemist inside me to burst into happiness.
Oh man, I really wish that this was a slo mo guys collab. Still a fantastic video, though.
I have done this on my old work with acetylene, also blended with oxygen. And filled into a 5 liter jerycane. That was a nice bang.
Not recommended without ear protection.
I have a rather curious substance discovered from a Oncorhynchus nerka. This is the second time i've come across the substance.
The substance looks transparent and is rather brittle, its appearance and surface is like a "crystalline quartz structure" or some kind of salt crystal.
When heat is applied for 5 seconds from a cigarette lighter, it immediately changes colour from transparent to brilliant white.
I have limited samples if you would like them. Now i intend to look for more.
We did an experiment in school where we bubbled methane through soapy water, picked up the bubbles and threw them in the air right as we lit them
Neils bubbles are the best!
I really enjoy your videos, keep posting!
Have you ever done it with Acethylene? the gas used for welding and cutting?
I noticed the slow-mo has periodic videos labeled in the corner, clever way to fight free booting
Please indicate the ratio of playback framerate to capture framerate or include a timestamp on your slow-mo shots. It's impossible to gauge time scale otherwise.
I love all these series Brady Haran and co have on various channels.
While watching this video I had a question come to my mind that I would love for you to explain. What is the chemistry behind the formation of bubbles, or better yet what is the role of surfactants and lipids on the development and stability of bubbles. I do not ever remember anyone discussing this and I will have to look into my text books.
You need the Slo Mo Guys to bring their cameras to Nottingham and redo the explosion. It would be interesting to see the structure of the flame front.
That is incredible.
use an ethyne torch next time :p
You might want to turn down the volume near 0:42, 1:32 and 2:26 cuz this scared the heck out of me >.
What about a mixture of hydrogen and oxygen? Will the bang be harder?
do acetylene and oxygen bang!
Why does the flame have to be lit when you put it into the soapy mixture? If it just goes out right away?
Love the vids!
I did this, except I used my water splitter to generate the gasses, however, because of that, they were hydrogen and oxygen, a more powerful mixuture, and it was really loud.
Not to slight the boys at Mythbusters, but the good Professors' crew blow things up right off the top whereas the other guys wait til, what seems, the credits roll before they blow something up.
Can you talk about Dioxygen Difluoride?
Interesting to see the different pronunciation of methane. Me-thane or Meth-ane
Come for the explosion. Stay for the professor.
I'm curious as to why the torch must be lit before going into the soapy water. Is it only to keep the mixture of methane from escaping into the room or does it serve another purpose?
***** That makes sense that it is a fire hazard but wouldn't you just then start with the end already within the soapy water before you start the gas flow?
Will this work with propane?
Why must the torch have to be burning to do this, it would seem that the gasses would mix if no flame?
I think Safety reasons so that the Highly explosive gas does not just explode, it better Burns down in a Controlled manner .
Because you aren't supposed to have an unlit gas source that is flowing.
By having a flame and looking at it you can adjust the gases so its the proper ratio betwen ox and fuel. So when you make bubles you are shure its the right mixture for the efect you want.
Kaine Bishop
But what about when you take it out of the soap, it would still be flowing unless you had a switch on the handle, in which case the fire wasn't necessary to begin with since you could just turn it on with the nozzle already in the soap
DavidMadsen You turn it off before removing it from the water
Can you tell me a nobelium joke?
No
Can you tell me a Ytteby and Einsteinum joke?
YEs
Can you tell me a potassium joke?

Can you tell me a joke abotu when potassium and oxygen meet?
OK
Can you tell me a joke about open-ring shaped diamonds?
C
Can you tell me a joke about Reversed Septuraniumhydrogensulfate and Uraniumphosporate?
SHU7 UP
Can you tell me a joke about metallic thorns?

POOP
LightningCat Craft Can I tell a nitric oxide joke?
NO.
Just Multiply Nitrous oxide isn't as funny.
seems like what my highschool chemistry teacher would pull off to get us to pay attention
Detonation or Deflagration?
That is wonderful professor to explain how to make explosions. Please make more videos of how to make explosives. BTW my girlfriend says you look really handsome with that funky hair style. ta blesses Arek
Get SlowMo guys to collab or something!
Samantha is such a fiery lass. :-)
So, an explosión is a quick combustión reaction?
I get methane explosions after eating baked beans with tobassco sauce.
for occasional celebratory joviality at remote mining sites we would take the large and thick commercial garbage bags and expand them with the cutting mixture from oxy/acetylene tank, then seal them with electrical tape.
we would then take the bag, hang it off a stake pounded into the ground, back waaay up and shoot the bag with a flaming arrow. Warning .. this could kill or maim you . hearing and eye protection highly recommended.
can you do a video on Fluoroantimonic acid?
Pleaseeeeeeeeeee
Do it with acetylene.
So, If I bring a huge tank of LOX onto the surface of Saturn moon Titan and release it, then light it up, would the moon become a giant bomb?
***** Is this a task for you??
Try it with acetylene instead of methane. Its a better bang.
Hey it’s Walter Cortez
I wish periodic video will be more about chemistry and less about explosions...
fscarp true. and im intrested in the reaction, not in the COOL BANG of the reaction
How does the oxygen get in the bubble?
the methanetorch blows methanegas and oxygen and those two combined makes a very hot flame
The torch has two tanks: oxygen and methane. They all come out the same tube, which is why the torch burns hot and effiecently, perfect for welding, and why the bubbles explode instead of burning.
what happens if I blow in oxygen and hydrogen instead of methane?
Did this, better bang.
Acetylene and oxygen in a garbage bag equals a few windows blown out at school and a few teachers needing new underwear, along with quite a few pupils........ Was not me, I saw them placing the bag out and ducked behind a concrete pillar just before the window shattered out into the quadrangle, followed by a bellowed "You B_____rs" from the slightly excitable teacher upstairs who had just about had a heart attack.
SeanBZA My school is far too boring for something like that to happen. Also it's TH-cam, no need to omit cuss words.
RedInferno112 You don't understand, that's what the teacher actually said.
Yeah, i am never comfortable in a house that has acetylene bottles in it
SeanBZA When I was a teen years ago, I bought a carbide cannon, into which you placed water and added a small scoop of powdered Ca carbide, When the cannon's breech was closed and the flint striker produced a spark, the acetylene it produced was ignited, the report was truly deafening, and the flash lit up my neighborhood at night! Only now do I fully realize how dangerous it really was!
best hair removal method? XD

Experimenting with mathane must be excruciating, with the smell of fart all over the place, haha!
Turtle Herder I had no idea, thanks!
***** Well, I usually get it when I had a bit too much coffee while doing some math, the combination makes it slightly better than normal methane.
Turtle Herder "The smell is an additive for safety." I guess that fart smell is not an additive for safety at all. And that was what he was reffering too.You're totally right in the case of "gas" which comes out of gas pipes. The "gas smell" (tert.-butylthiol) is indeed for safety reasons.
Turtle Herder
Was it a lorry load of brussel sprouts? Seriousley, What is the additive? it seems to permeate the materials in old cooker pipes etc, so they still smell 5 years later.
Sirus It's a mercaptan of some sort. Usually Methanethiol: CH3SH (often called methyl mercaptan) or tert-Butylthiol (t-butyl mercaptan)
Can we make
you need to borrow slow mo guys 1million fps camera :p
British people say "meethane" yet not "meethamphetamine" :P
Methane and O2 is more of a detention than an explosion imo.
Green Silver I think you mean detonation ;)
Green Silver Depending on your definition, it can be labeled as either a detonation or an explosion.
It is both an explosion and a detonation a detonation is a
Detonation (from Latin detonare, meaning "to expend thunder") is a type of combustion involving a supersonic exothermic front accelerating through a medium that eventually drives a shock front propagating directly in front of it. Detonations occur in both conventional solid and liquid explosives,[1] as well as in reactive gases. The velocity of detonation in solid and liquid explosives is much higher than that in gaseous ones, which allows the wave system to be observed with greater detail (higher resolution).
An extraordinary variety of fuels may occur as gases, droplet fogs, or dust suspensions. Oxidants include halogens, ozone, hydrogen peroxide and oxides of nitrogen. Gaseous detonations are often associated with a mixture of fuel and oxidant in a composition somewhat below conventional flammability ratios. They happen most often in confined systems, but they sometimes occur in large vapor clouds. Other materials, such as acetylene, ozone and hydrogen peroxide are detonable in the absence of oxygen; a more complete list is given by both Stull[2] and Bretherick.[3]
Processes involved in the transition between deflagration and detonation are covered thoroughly for gasses by Nettleton.[4] If the explosion went supersonic then it propagated a shock front , the torch was the deflagration and the rapid explosion was the detonation ..
Backfrom Thedead How much of this was copy+pasted from Wikipedia? Be honest. I can see those citation marks [#].
***** It was copied and pasted those are the correct definitions .
Brits say "me-thane". Yanks say "meh-thane".
bubbblles meethane
"Pow!"
Dangerous information
acetylene works best
can we make farm out of it?
meh, show us more about thorium!
Heh fart ¯\_(ツ)_/¯
#slow mo guys
I want HURT!!!!!!
Don't try this at home. LOL
he looks like
science
I had a Methane explosion over here if you know what I mean :)
sorry...
Spare a thought for the poor people (men, women and children in early 19thC British coal mines for example) who were caught up in methane explosions. Yay for canaries and the Davy lamp!
Then again...exploding cows. Bummer.
Neil bubbles >> Sam bubbles.
