  • i would go crazy with all the humming and talking i hear in this class!!!

  • spontaneous Combustion what exactly mean?

  • Y U NO BLOW UP?

  • We did this today with bromine and iron it was so cool!

  • I would sprinkle that stuff everywhere around a dangerous fire, the nwhen someone tries to put it out, it starts a bigger fire. >=D 

  • WHY DOES SPONTANEOUS COMBUSTION HAPPEN?

    WE KNOW HOW BUT WHY? Find out.

    Know More

  • wow an ad in the video that you cant close... nice one dicks

  • BURN THE WITCH WITH HIS OWN TOOLS

  • omg hes a witch :O

  • I would like to buy your dehydrated fire...

  • Thumbs up if South Park brought you here :P

  • So if you can't put the flames out with water, what do you use?

  • @pryrstlwrks fire extinguisher??

  • @pryrstlwrks MOAR FIRE!!

  • i am 12 but i want to know MORE

  • Southpark brought me here.

  • i just dont get why all of them are coughing non stop

  • imagine a dude in the background screaming at the animator: STFU AND GIVE ME SOME FIAR!!

  • SCIENCE

  • Purple flames > blue flames > regular flames

  • tell the people to stop coughing!

  • Why hasnt anybody used this technology to make a self-cooking hot pocket?

  • i thought about going to Carleton...

  • Do you think that people who hold fart too long can get ignited?

  • FART!!!

  • I once saturated some cotton dish towels with linseed oil, put them in a small box with an open top and several holes in the bottom. It stunk up the neighborhood all day and in about ten and a half hours it burst into flame.

  • it was funnier if all the place went up in flames

  • @lexmark136 This was a public event, not a lecture.

  • that does not look very spontaneous

  • @r0llskyay0 I was about to say. What makes this spontaneous?

  • @r0llskyay0 The definition of spontaneous combustion requires that no excess energy is added- you can't heat it or compress it, for example. You simply mix the materials and they ignite. There may be a delay, or induction time, before combustion occurs. Spontaneous combustion does not have to be instantaneous combustion.

  • @jmanthorpecarleton Spontaneous= Random

  • @wtfruo99 Spontaneous=Impulsive/random when describing a personality trait, but chemically speaking, it means the reaction will occur without adding energy to the system

  • A spontaneous reaction can take years or seconds, but what matters is that it will proceed by itself. A metal pipe rusting is a spontaneous reaction, but that doesn't happen overnight, does it?

  • @r0llskyay0 There's a great SERIOUS book called (oddly enough) "Spontaneous Human Combustion" by JENNY RANDLES & PETER HOUGH. Copyright 1992 by Randles and Hough.

    AMAZON.COM HAS IT. I'm told "error" when I try to post the link.

  • Fricking criticizers.

    =.=

    Great video, I really liked the second flame. 5/5

  • Is that an alkali peroxide?

  • whoa

  • blue flames > regular flames

  • Whoa!!! It was blue!!!! =D!!!

  • Lol isn't it when you just randomly set on fire or sumffin like dat?

  • how is it spontaneous compustion if you have to wait awhile (first experiment)... doesnt that kind of defeat the purpose? or do i have the wrong meaning fo spontaneous?

  • You have the wrong meaning of spontaneous combustion

  • Why would you be using a hot plate if it wasnt plugged in ?

  • So that it doesn't burn the table, retard. He just fucking said that.

  • can't believe you are impressed with that all he did is mix either K or Na with water

    this two elements highly react with water you can see it here just type k bomb

  • Actually Nekito16, neither one of these involves K or Na metal. I also posted a video of that reaction. The dead giveaway that's it not K or Na metal is that the metals are shiny. No shiny metal in this video...

  • @jmanthorpecarleton what chemical is used

  • @jmanthorpecarleton is this stuff avalible to the public?

  • @Nekito16 I think we all know it's not magic.

  • this happened today close to where I live in California, too much manure lying around fermented and the 106 degree heat didn't help

  • yay applaud science!

  • heat isn't needed, it's an ignition source that's needed and the two chemicals reacting is the ignition source so is normal combustion in that sense

  • wrong normal combustion requires 3 things, fuel, oxygen and heat... so wheres the heat? This isn't normal combustion.

  • Correct me if I'm wrong, but I do believe the heat is coming from that hot plate its on at 0:49

  • You are wrong as stated several times in this thread...

  • how many times do i have to say it.

    Spontaneous means randomly occurring, and in the beginning of the video you see him putting all the chemicals together. The first one was started with water and the second one was a slow reaction as he said in the beginning of the video. so it wasn't random, its just slow.

  • Actually the hot plate isn't on. It's not even plugged in. We just didn't want to melt the table.

  • i dont know all this stuff i just like combustion spontaneously! (lol)

  • i love the beach boys!!!

  • Actually Cazbahh, it wasn't sodium or potassium in either case. Even if it were sodium or potassium that reacted with the water, it would still be spontaneous combustion. The energy released by the reaction of sodium or potassium with water would be internal energy, not external. External energy is something like flame from a lighter or Bunsen burner or heat from a hotplate.

  • what is that plate (connected with a cord) on the bottom of the bowl for?

  • It's just there to absorb the heat so the table isn't melted. It's not even plugged in.

  • Unlike the people below me, I dont learn from television.

  • The only reason I'm watching this is beecause I got interrested in this when I watched Fringe

  • I watched fringe also and thats why im watching this. Do you mind telling me the summary of what happened in that episode of fringe, i stopped watching because i got busy.

  • That's the reason I'm watching this.

  • Well this girl couldn't breathe and she got on a bus when she looked at things it would either catche on fire or melt and then she caught on fire and exploded and also her twin sister also exploded and one of the members in the FBI kept seeing visions like the city on fire and seeing 2 bodies in when she exploded.

  • lol i just saw it happen on fringe a couple seconds ago and i was like WTF. now i wanna know too haha.

  • whats the ingredients

  • I think it's calcium carbide. When react with water it releases ethyne wich catches on fire.

  • yes, but you need a flame source to combust ethyne

  • ok you need water to put out a fire, not necessarily. theres foam and CO2 and such

  • oooooh! pretty colors!!! lol

  • what is the "solid compund on top here" said in 0:53 i need this for a science project, please respond soon!

    Im doing it on spontaneous combustion:P:P:P

    awesome vid, btw...

    thx!

    -Nina^_^

  • not something this university would like to be responsible for i think, as it can be used under pressure to make bombs. call up the chemistry faculty and tell them your student status, im sure they would tell you then.

  • @totallyleafy lol after a year they still didn't reply... real cool

  • @APOKOLYPES

    ahah no worries they did - they just coulnd't post it publicly for safety reasons

    and it really helped my science project

    so all's well :)

  • @APOKOLYPES now two years lol

  • How is it spontaneous? He put flammable ingredients together and watched them burn. It's just combustion. It shouldn't have been called that.

  • Actually, spontaneous combustion is defined as combustion that requires not external heat to initiate combustion. Neither of these reactions were heated; therefore, they are, in fact, spontaneous combustion reactions.

  • hey isnt that ingredient the thing they use in fight club, you know the shit that burns the dudes hand when they add water and then use vinegar to stop the reaction?

  • you mean LYE????

    that shit reeks!! dont get it on your clothes!!!

  • intresting..very interesting!

  • Those are suppose to be impressive? they are just extremely exothermic reactions.. duh...

  • what materials did he use?

  • In order to have a fire you need to have a combustible material and an oxidizing agent (usually just the oxygen in air). In most cases you also need a source of ignition. The examples in the video don't need an ignition source. The combustible material in the first example is cotton. By adding water we generate heat and create a high concentration of oxygen gas. This causes ignition. The second example uses glycerol and a different oxidizing agent that will remain my secret.

  • waters supposed to put out fire!!

  • not alkaline metals

  • that's very interesting. where was this held at?

  • This was held at Carleton University in Ottawa, Ontario, Canada.

  • incredible
