Why does the water ACTUALLY rise??

Check out these FOUR experiments and multitude of chemistry and physics facts that help create an explanation for the famous covered candle suction experiment. If you have never covered a candle sitting in water, get ready to have your mind blown. It takes chemistry and physics to explain this phenomena. It is easy to do at home (so try it!), and very safe! Discover how the combustion equation of a carbon compound and the thermal expansion of air lead to the water rising in the jar that covered the candle.

This is such a fun read on this experiment! It is why I wanted to do this experiment. I highly recommend checking it out. The other paper (listed below) I found from his blog.

Paper by Harkirat S Dhindsa
A very informative read on this. It gives a lot of fun ideas and things to reflect on and potentially test.

Another great experiment FlemDog, love the longer videos. Really interesting stuff, thought I had it all figured out but no, its really a crazy process.

[@Nash1a]

At the end, I would suggest the reason why it rose so fast is that once the flame was put out, the air condensed. Based on that I would presume "breathing" had to do with a struggle for equilibrium. Maybe as the pressure changed, the flame was retarded. Each time a bit more water was sucked in the flame was affected a little more allowing the water to rise further each time.

[@flemdogscience]

Do you have any idea why the water went up and down and up and down in the final large flask?

[@bananachunk5336]

I can’t repeat the big words that dysject said. I don’t know if it’s jargon or he looked it up, etc. But I believe it’s somewhat correct, the container is large enough for air currents to form but I have no idea why it would fluctuate. In my head the pressure would remain the same in the whole glass, but is it due to the air current that pressure fluctuates slightly allowing the water to rise and lower even though pressure is decreasing the whole time?

[@dqstechtoonz4888]

i didnt watch the whole vid so dont blame me if im wrong but i know heat rises so i thing the water rises with the heat from the candle

[@dqstechtoonz4888]

no idea why it went down

[@AuroraDreams_]

Fontainians be asking the same question

[@danquist5085]

I would be interested to see the big flask tested with a variety of candle lengths. Something makes me think a candle going just past the neck of the flask would be the coolest.

Also matter can't be created nor destroyed

[@NaliTikva]

Actually it can, E=MC2 Not new science

[@John77787]

That was a dope experiment.

[@frogz]

not first not first not first, its my phobia to be first

[@frogz]

doesnt KNO3 contain quite a bit of nitrogen? ;) the reason it rose in phases is because you were creating a seal at the bottom of the plate against the styrofoam, if you only have a little water on the plate, enough to create a seal but not enough to put the candle out, it would probably bubble for a while before the candle actually went out as more and more air got sucked in until all of the air in the flask was used up and what little it could suck it wouldnt be able to sustain it for long

[@flemdogscience]

That is a great idea with the seal. To prevent that (because it had happened with the little flask a couple times) I kept the flask tilted so water could freely enter. Any other ideas of what it could have been?

[@justTheBonnieboii]

Lol

[@Mr_Booshy]

I wasn't gone. Saw all the way through. Saved the best for last. Need to revisit that last experiment with a video explaining what you think is happening.

[@Starsuur]

Underrated

[@someperson7]

Concision is valuable.

[@RudJam]

For the smaller bottle, was it the co2 that lit out the flame?

[@James-uw4it]

Awesome thanks for the experiment
