Why some of the kernels in your popcorn don't pop

No matter if it's popcorn you've ordered at the theaters or popcorn you've cooked in the microwave, there always seems to be leftover kernels that didn't turn into popcorn. Physicist and author of "Storm in a Teacup: The physics of everyday life," Helen Czerski, explains the science behind this mysterious phenomenon.

Reheat the popcorn so it then pops. It may be burnt afterwards but hey, popcorn is life.

[@therbz]

They literally said that it can't be popcorn because it had leaks. You can't fix a leak doofus.

[@iamsorrybut2370]

tape it

[@Primalxbeast]

I am sorry but Don't be silly, using tape wouldn't work. You obviously need superglue.

[@queensmari4805]

TheRBZ but i reheat unpopped popcorn all the time-_-

[@deadfr0g]

Silly piece of trivia: Apparently, within the popcorn industry, kernels that don't pop are unaffectionately known as "old maids." When purchasing kernels in bulk quantity, the expected percentage of old maids is an important thing to know because it directly affects your profit margins.

[@a-bird-lover]

I eat them anyway

[@subscribetomefornoreason6188]

Your teeth must be strong to chew up that seed

[@aangwinoto96]

The lollipop of Kim Taehyung Yeah, I ate them too, on June I'm going to meet a dentist because I breaks 4 of my teeth, 2 of them because of chewing these devil. Brushing your teeth and chew some chalk turns out to be important, regret not doing so.

[@subscribetomefornoreason6188]

I love eating them!

[@bagdaja6881]

when I reheat them they pop up

[@Fact_core]

Bagdaja
don’t do that

[@temqwerty]

I used to eat a ton of popcorn and started saving the unpopped kernels. I reheated them after I had a lot and they popped fine :o

[@harshamannepalli3]

The darkness that filled the room when she said 'And they will never become a popcorn'

[@leonchen7707]

Ok I'm sry, I'm too lazy to put it in the microwave again so I just eat the kernals. XD

[@limeyfigdet7460]

I hope you don't crack a tooth.

[@queensmari4805]

just save em in a jar :P

[@spookwavevevo]

Leon Chen Even if you did put it in the micro again, they wouldnt pop.

[@britannic124]

Leon Chen They still wouldn’t pop. Did you not watch the video?

[@chilongqua1238]

What a lively presenter. Well spoken and articulate.

[@robloxahyaanadeel]

I microwave my popcorn 4 times, whenever the kernels are left, I remicrowave them until I reach perfection

[@silvertown9324]

Good to know, however why does this happen? I shop for kernels from one and only shop, every time I get them perfectly popped. What's wrong now? Were they too old or something? Or have I kept them for too long in my cupboard?

[@nathanhong7592]

is it just me or whenever I find the kernels on the bottom I put them all in my mouth then spit it out yelling BUBBLEBEAM

[@moelester7971]

When I was little I thought I had to keep microwaving the kernels until every single one popped. I tried it until my house popped.

The Saddest Story of them all

[@two-shots3972]

Wow thanks for telling me this awesome fact!

[@EVILGOKU1986]

This is cool to know. I won't leave it in longer, always felt it just needed more time.

[@mrwavelord8963]

That leak won't stop me from eating it

[@cndvd]

Well she is kinda right (don't want to say she is wrong). I did a test, and they do pop in a pan with oil. But they only pop about the 1/4 size on average, but they do "pop". And it's not worth popping them cause of that. Plus, they burn all of a sudden, so you have to take it off the burner fast. So they are like reject kernels. But maybe find those ones that are just partial cracked open turn up. Those are nice to eat, the crunchy ones.

[@yiningOo]

thanks for sharing ❤

[@HaloHighlightz]

Never say never. If you re-pop, a lot of them pop 😂

[@superhuffpuff]

When she said pop something fell and it scared me to death

[@kokwengleong2303]

'And they would never become popcorn'...so sad😢

[@phatboied]

Thank you

[@pparkeroni]

I like eating the unpopped kernels tho, sometimes i chew them but usually i just swallow them whole...

Leak or some of them are too dry to the point that there is no enough water inside to burst.

[@soulassassin0g]

I like those slightly unpopped popcorn, the ones that look like they just didn't have enough time to expand.

[@renaldiroekanto789]

I have eaten that. Will it grow in my stomach?

[@Trufflestravels]

How can i pop popcorn half way?

[@lisadooley3872]

I wonder what the unpopped kernel feels like because it didn’t become the white fluffy popcorn

[@rat_king-]

Place all in water, Remove water from bowl reinsert into your prefered heating method, microwave, pan, special machine, and then serve

[@winonadaphne6445]

wow that's fascinating!!!!

[@TheMADC999]

But why does it pop when I cook it separately on a pan with oil?

[@renesteeman1]

Ma Cas The oil fills the holes and water and oil don't mix as well as the oil being more dense, so it will push the water down, so the water still can't get out.

[@elephant_lover358]

Really? I reheated unpopped shells before and the shells caught fire instead.

[@TheMADC999]

林淳信 lol thats funny. I dont know

[@grisellhernandez4558]

Whenever I see those kernels...
*I swallow them like LEGIT pebbles*

[@COHOFSohamSengupta]

I've been waiting to know this for millions of years....

[@themandalorian6758]

U can use the unpopped kernels and pop em up and u will never know the difference of it

[@ttv7927]

Kernels are my favorite to eat

[@jokrwx3]

and how to solve it ?

[@assimilationsynthesizer]

Maybe you can use the unpopped kernels for something like chicken feed

[@jaybird1650]

They aren't hot enough since they were covered by others and also some might have stronger shells.

[@XY2Moroccoball]

So that's why sometimes when I'm eating popcorn, some popcorns have some weird liquid on them.

[@JellyDaisies]

it is truly one of the saddest tragedy of our lifetime.

[@luckky2983]

What if you put a water then?

[@jdbest4553]

I love the unpopped stuff tho.

[@doggosarecool7737]

What about popcorn kernals that are a bit popped

[@limeyfigdet7460]

I'm a rebel. I reheat my popcorn in the bag even though it says not to reheat un-popped kernels.
Sometimes leaving the kernels is too wasteful, and if you heat the whole bag up more the first time, the earlier popped kernels burn a little.

[@sovaros78]

I was eating popcorn while watching this

[@MarkdoBrasil]

Damn it.

[@biancabynightx3799]

That last sentence was so sad 😞😥

That makes sense :)

[@chawlay8208]

Can we repop again until pop?

[@Yenni374]

The butter popcorns are so goooood😅

[@keencloud7456]

I only used normal corn and it taste good

[@danielherron5597]

omg i cannot stand anyone thinking the plural of popcorn is 'popcorns'

*Press F to Pay Respect*

[@eliteevildarkness5830]

Her sad face at the end tho 😭😭

[@tessemi]

They can still be eaten.
But half popped ones are the best.

[@whatareyoulookingatwut6460]

Easy I paused right when the video started because I already learned this in class"
Some popcorn kernels are dont pop because some don't have enough water in them the water evaporates and that's what makes them pop if you want them to pop you put a little bit of water in a can container etc leave it over night pop it whenever if there is still kernels do the process again.

[@THEGAMER-cc2eq]

0:18 She could have said moisture instead of water

[@Russia_Moscow_countryhuman]

Or when you bite down on one and it doesn't pop fully, so you bite down on something hard

[@leepambid9658]

My friend put the leftover kernels in the microwave it acctually popped

[@Dog-the-lucky]

That true…

[@tanngerin]

so tragic

[@ajaysumbing]

now i can rest happily

[@thepenguin2118]

Rip popcorn

[@jrzzrj]

Some un-popped corn kernels will pop, some won't. Not worth saving and trying to re-pop them.

[@sslavi]

The ending part is so sad.

[@epoizparadigma8986]

and how to solve that

[@gasdorficmuncher9943]

r.i.p unpoped sadly missed
