What’s in a candle flame?

In a candle flame there are electrically charged particles, which you can pull apart using an electric field.

The two streams of smoke is really interesting. I learned something.

Fun fact, this is how your furnace knows if the fire is lit or not. The flame sensor has a 90v AC potential on it, and this 90v is shorted to ground through the flame. The control measures the current and can determine if the fire is lit, or if it needs to try again.

Oh, I love how he consistently uses the metric units. A true scientist.

Why would anyone dislike this? This is a great demonstration of physics and chemistry fundamentals.

Ok now i want Slow Mo Guys to film that

The visible arc literally is the air on fire.

Both fire and lightning together. Uchiha clan would be proud of this man.

My understanding of fire took a huge jump today. Thank you.

This explains why the smoke always chases me.

This principle allows flame rectification gas cooktops to monitor for flame and relight themselves if the flame goes out for some reason.

Great demonstration how an 'electric filter' works.
The gas/dust particle are sucked to either side of the electrode. 👍🏻

[OriginalRaveParty]

I love these kinds of practical demonstrations of science

[aurinator]

Excellent video and something I've always wondered - what a flame was composed of.

[maniknath]

Another video more informational, educational and enjoyable than a whole book we all studying in school.

Have you ever seen a wildland fire under a high voltage transmission line? At first, the smoke conducts the voltage to the ground, then an arc forms within the smoke, shorting it out completely to ground. Very spectacular!

I remember fighting an argument over fire being plasma or not. This cleaned my statements in an experiment. You did well for future science warriors Sir Veritasium! Grave Thanks & Respect!

Electricity: I'm faster than you
Fire: Let me create you more siblings.

[atifashhabatif]

That's amazing! My goodness, this universe is just full of too many things to learn

I work for a water heater manufacturer, we use a process called "flame rectification" for some of our product. The process involves sending electricity through the flame, to ensure that the flame is actually there. No flame, no electrical pathway, an error code alerts the owner that there's a flame issue.

What a great activity to understand plasma better !
