How do piezoelectric butane lighters work? | Physics | Fran Scott | Head STEAM

Almost everyone's used a click lighter to light their cooker, or their barbeque. But how do they work? Well, it involves one of Fran's favourite physical principles, and to show us she takes it apart. People, don't try this at home.
00:16 First, she has to take it apart.
00:37 Now, she has the internal workings of the lighter. Butane provides the fuel, and there are wires for a spark. But how is that spark generated?
01:17 The spark generator doesn't use a battery. Instead, the spark is generated by piezoelectricity, a property of certain crystals that create a charge when they're bent or squished. The difference in charge leads to a potential difference, which we know as a voltage.

02:28 So, in the lighter, the spark is created, it voltage is created, travels down the wires, and creates a spark.

I like the way she says "cooker lighter".

[@dhirajgupta9802]

It took me half the video to understand she is saying cooker lighter :D

[@marylim381]

Me too, thought she was saying coco(a)😅

[@fishcamptv]

Exactly what I was looking for, thanks! 😍

What I’ve been wanting to know. Good vid

Piezoelectric = Absolute Genius :)

[@NativeVsColonial]

Or Pressure Electric :)

[@yonicohen11]

Perfectly explained. Thank you!

[@mohannadali6828]

Thank you so much I’ve been wondering what’s going on with that

[@emlynjones9393]

Absolutely brilliant explanation, I only wish you had been my physics teacher!

The trigga of the cooka lighta

[@deepdoubts]

Ill keep this in mind the next time i light up my bong ... trippy

[@Juanah92]

The camera was too distant.

[@iisdan]

I learned something!!!!

[@ridwandani4094]

Can spark generator fix if it get weak?

[@chriscycles6845]

hey head steam, I have a question, do those piezoelectric cryztals wear out over time? someone please answer, big help

[@fatihgulduroglu4654]

six years have passed since you posed this question. kindly inform whether yours has worn out for the sake of providing a pieze of data to science

Yes they do wear out over time.

Thank you for explaining this. I'm now going too turn this into a mini hand held flame thrower hiddin in my fist
(it's not being used for anything bad just too show off too my friends and family)

[@jacobcronk1844]

first idea i had when i ripped one out

[@NerdThingsAndMore]

Thanks

[@trustchemistryiitjeemainsa449]

Extremely well explained

[@jozefnovak7750]

Super!

[@GoodBman13]

Wow I guess crystals can have energy in them

[@Xc0m]

Whats a cooka lighter? :)

[@mr.engineear0987]

Ya mum

[@slingshot909]

Very nice explanation, I love learning how things work, and I love your accent-I know its not an accent-right? but its different from mine, lol, cheers!

[@NeuonAu]

Excellent editing!

[@kausalyakalyanasundaram6122]

very useful

[@JesusSaves734]

It's been years. You good? I noticed that there hasn't been a post in over 6 years

[@wh0586]

Can this not be used as a mass energy source?

[@deliciousbutter6077]

It doesn't actually loss mass, it just converts the force of your hand into an electrical current.

[@minnaaa7273]

My brain stopped working when she started to explain. It was interesting though...Even though (for visual learners) it would be better to insert some presentations. I cant follow specific explabation without a chart.

Coocka lightah

i heard it as calculator

[@film79]

Lol, I come back to this video often just to hear her say it

[@bradybg7369]

I think I saw you on Science Channel

uhm if I can't do this at home, where should i do it? at my granny's house?

Yeah

thats coool

cooker lighter?

can we use it for continuous flow of current?

Cooka lighta.... 😳

I done this at home, but instead of using screwdriver I used a hammer like Jeremy Clarkson would.

i actually thought she was going to smash it, i was disappointed to see the screw driver.

The cameraperson needs to keep the object in view, not the woman. Unless we're here to look at the woman, but I came to learn about piezoelectric butane lighters.

[@bizzytokin14]

looool "dont try this at home" how damaged do you have to be to hurt yourself taking apart a bbq lighter....

tf happened to ur eyes?

Tried to watch it, but her accent drives me crazy.
