      legion2k I had a friend who pulled a prank like that on one of her profs at college. She put a piece of a hot dog into the finger of her lab glove, froze it, then tucked her finger into her palm and wore the glove (so the hot dog looked more or less like her finger), then smashed the "finger" and screamed. Her prof saw right through it but her classmates FREAKED. One of them fainted. ^_^

    • @JeffersonLab
      @JeffersonLab  9 лет назад +226

      Yep. And, if you didn't know that most fires need oxygen before now, you've learned something! That would make those eight minutes a good use of time!

      Big Bang. The quark-gluon plasma cools, allowing nucleons to form. Clouds of hydrogen and helium gas collapse, forming the first stars. The largest stars explode, seeding the Universe with heavier elements. The sun forms. The earth forms. Life arises. Life evolves. Dinosaurs rule the planet. Dinosaurs are wiped out, allowing for the rise of mammals. Life evolves. Humans create language and art, master fire, build tools and learn agriculture. Civilization arises. Humans aren't completely occupied with survival, so there's time to discover how the world works. Chemistry, physics, biology, math and all of the other sciences develop. People learn how to liquefy nitrogen. RUclips is invented. A video is made of a lit candle being placed in a container of liquid nitrogen. The video is uploaded. You click on a link. You arrive here. Elapsed time, about 13.798 billion years.

    I don't get why there are so many dislike. He obviously knew the candle wasn't going to blow up. He wanted to make the kids feel agitated and expectant, only to throw them a disappointing fact that nitrogen doesn't catch fire. It's how people will learn.
    Or was it because he didn't dip the burning candle into the liquid?
    There's really no point. Nitrogen, liquid or gas, simply won't explode or catch fire.

      How so? If you were expecting it to explode, then you are lacking an understanding in how fire works and you used that time to fix that deficiency. That's a win for you. If you knew what was going to happen and you watched anyway.... Well, that was your choice.

  • @th3kr3w100
    @th3kr3w100 9 лет назад +27

    I deeply appreciated this video. I am in college majoring in science, and I had picked the "N2 will just put out the flame option", but was still on edge and built on suspense that I was probably going to be proven wrong, SOLELY based on the fact that you seemed to be inferring that an explosion was going to happen. Not only had I anticipated an explosion the first time, but also the second.
    This video really teaches the importance of learning how to think for yourself and trusting the laws of the universe to be able to predict outcomes, and not the spoken word of somebody else. I also think you made the whole experiment much more exciting through your presentation, and more likely to be remembered than if you had presented the experiment plainly. The result was honestly disappointing, but if one could see the beauty in the disappointment, a deeper appreciation for our judgement could be obtained.

      Gregg Macey If the title were "Liquid Nitrogen + Fire = EPIC EXPLOSION!!!" or "My jaw hit the floor when fire was put into liquid nitrogen and then THIS happened!!!" then, yes, I would agree that those would be leading you to expect something... grander. As it is, the title consists of four words, three of which directly describe what's being dealt with in the video. The fourth word is a conjunction and can't really be faulted for being there. If those four words caused you to expect an explosion, it's because you JUMPED TO A CONCLUSION based on the minimal, factual data you were given. The jumping occurred within your own head and isn't the fault of the title. Disappointing? Sure. But that's sometimes what happens when one jumps to a conclusion.

    Nobody twisted your arms to watch this video. These are 8th graders, or so was mentioned in the video. A lot of people making troll-like comments about wasting their time, you look a lot older than the 8th graders. Try saying something that helps with the conversation instead of whining because you were expecting an explosion and it didn't happen. A little common sense and maybe a little research will get you a long way.

    At the beginning when he asked the kids what would happen, i knew right away. We learned this in IPS, when we read a book called the Disappearing Spoon. For fire to stay lit, it needs oxygen, which is flammable. Nitrogen has the opposite effect, it snuffs out the fire.

    • @JeffersonLab
      @JeffersonLab  9 лет назад +6

      Joe Nagle Oxygen is not flammable. Oxygen does not burn.

      Jefferson Lab Pure Oxygen is flammable.

    • @JoeNagle-Bagle
      @JoeNagle-Bagle 9 лет назад

      Yes, and what i meant to say was that nitrogen puts out the flame, and that fire feeds on oxygen. When there was no oxygen the the tube, the fire went out.

    • @JeffersonLab
      @JeffersonLab  9 лет назад +1

      MCAA6556 Pure oxygen is not flammable. Without something to burn, the oxygen has nothing to react with and there's no fire. Take a look at the video where we put a lit match in liquid oxygen. You'll see pure oxygen *NOT* burn as soon as the match runs out:
      ruclips.net/video/1kLsNRPiqco/видео.html
      But, suppose that you're right and that oxygen were flammable. What would the reaction be?
      O2 + O2 --> what??

    • @JeffersonLab
      @JeffersonLab  9 лет назад +8

      While that would result in a boom, it wouldn't be as big as you might be hoping for. Like with the liquid nitrogen, atmospheric oxygen would be purged from the inside of the container. The only 'boom' would come from a relatively thin layer near the top where enough oxygen has mixed in.

    • @JeffersonLab
      @JeffersonLab  9 лет назад +12

      Spore Creature No, it's not nearly the same thing. The sun isn't burning like the candle burns. There's no chemical reaction with oxygen. The energy is a result of a *nuclear* reaction. Hydrogen is *fused* within the sun to produce helium, and the mass difference (4 individual protons are more massive than a helium nucleus) shows up as energy via the well known equation E = mc^2.

      Completely agree. I almost didn't finish my lady semester in college because I stayed home and just watched fascinating documentaries to subjects I NEVER was taught in school on RUclips and listened to audiobooks and things like that. When I would come into school it felt like a real joke and nightmare for myself - overcrowding, lack of materials, bad attitudes by professors and students alike, complete lack of information and worse, misinformation...money wasted to pay for overpriced GMO crap on campus and expensive metro fare. I have learned more on RUclips in 4 months than I had my entire 17 years in public school institutions. You have to teach yourself these days with America's teaching institutions collapsing and lack of book stores selling affordable books and closing libraries. If you are really curious and hungry for knowledge, there are public free databases (most require money) like jstor that will give you great academic articles on different subjects going back decades. Have a good one, and keep enrichment alive!

    Not sure why this video has such bad ratings. We need more educators like this to get kids interested and excited about learning. The great thing about science is that it doesn't have to be taught out of a book -- you don't have to READ about science, you can DO science. I promise you fully half of those kids went home after school and, instead of playing video games, watched videos about liquid nitrogen, and that's awesome.
