Anton: 我是一个发型师,我最新的发型灵感就来自于玉米上的白色物质,我称之为“玉米蓬”。 Kenji Lopez-Alt: 那些白色的物质叫做玉米须,它们是玉米授粉的关键。每一个玉米须都连接着一个玉米粒,它们从玉米顶部伸出,像海葵的触手一样捕捉空气中的花粉。花粉通过玉米须进入玉米内部,使玉米粒受精,最终长成我们吃的玉米粒。玉米须的形状像网一样,非常适合捕捉空气中的花粉。一个玉米穗实际上是一朵花,当花粉落在玉米须上时,它会向下移动到玉米穗中,使玉米授粉,然后长成玉米粒。我们吃的玉米粒是玉米的种子,为了让玉米生长,它需要来自其他玉米植株的花粉。玉米须的粘性有助于捕捉空气中微小的玉米花粉。一旦玉米须捕捉到花粉,它就会帮助单个玉米粒生长。

From the brains behind Brains On, this is Moment of Um. Moment of Um comes to you from APM Studios. I'm Anton, celebrity hairstylist. Um, um, um. I've styled the hair of many, many important people. Presidents, pop stars, even popes.

I don't just trim hair. I'm a hair artist. You want a hot pink mohawk with frosted tips? I got you. A sophisticated mullet with side-swept bangs? Easy. Double buns, Princess Leia style. Consider it a double done. Okay, I'm gonna let you in on a little secret. I have a brand new, never-seen-before hairstyle that I literally just invented.

It's called the corn poof. It's a little white ponytail on the top of your head that sticks straight up. So innovative and so fresh. And get this, my corn poof hairstyle was inspired by actual corn. You know, that little white ponytail-like thing that pokes out from the top of an ear of corn when it still has its leaves.

And then when you peel back the leaves, you know, the husk of the corn, there's all these little white strands inside surrounding the corn cob. It's just beautiful. Just perfect for my latest hairstyle. But say, what is that hairy looking stuff on the corn anyway? Brooke wanted to know this too.

So those are called the corn silks. Hey everyone, I am Kenji Lopez-Alt and I am a cookbook author and a children's book author. If you were to very, very carefully open up a ear of corn, peel off the husk and look at each one of those silks, you'll find that each one of those silks is actually attached

to a single kernel of corn inside. So every kernel of corn has a hair that is attached to it and goes to the outside. And in fact, those kernels of corn couldn't exist without those silks. What those silks are is essentially they're a pathway for corn pollen

to come down and turn into a new corn kernel. So corn, like other flowers, some of them will release their pollen, and then that pollen will travel over to another ear of corn to fertilize it. And the corn silks are essentially corn's way of catching pollen in the air. So if you think of like a sea anemone in the ocean, you know, it has all those little tentacles that stick out. And what those tentacles do is essentially they catch little bits of pollen

food that are floating around in the water. That kind of shape is really good at catching things like a net. And so that's what corn silks are. They come out of the top of each one of the corn flowers. So an ear of corn is actually a flower. When a piece of pollen lands on one of those sticky corn silks, it eventually will work its way down into the actual ear where it can pollinate the corn. And then that will grow into a kernel that you can eat. Um,

Incredible. The delicious corn kernels that we eat are the seeds of the corn plant. In order for an ear of corn to grow, it needs pollen from other corn plants. The white strands poking out from the top of the ear of corn are sticky, so they help catch the microscopic corn pollen floating around in the air. And once a strand catches a tiny piece of pollen, well, it helps a single kernel of corn grow.

Hmm. So I guess it's not really hair at all. Maybe I should scrap my corn hair ideas and come up with a different, never-seen-before hairstyle then. Think, Anton, think. Oh!

What about a lion's mane? Yeah, you grow your hair really long and then you fluff it up all around your face like a huge fluffy mane. Oh, or how about the mold cut? It's short and fuzzy and green. This is really going to revolutionize the hair art world.
