First getting a mohawk and then a backwards cap. Truly hank is becoming the ultimate cool guy

I vote Hank Green to be Earth's ambassador to the aliens cause he's the best of us

As a child I could smell rain coming. Now as a contractor I can smell water on concrete. Lucky me

Teslas don't have that "new car smell". They have that "Elon musk".

As an herbalist, my favorite smell is probably fresh rosemary. Like when I handle the plant and the leaves rub on me it smells amazing

The scent-emotion association is real and it's STRONG. I have my late mom's bottle of perfume, one sniff is enough to make me cry.

I absolutely love the smell of books.

Oddly, I really like the smell of tomato vines.

Hank is the ultimate 90s cool kid here, mohawk and backwards cap. If he starts saying radical, the transformation will be complete.

We need Scishow hats! And the proceeds goto cancer research!

One of my favorite smells is when bread is being toasted. While it's in the toaster, the smell always takes me back to my childhood and visiting my grandfather, whom I didn't get to see very often before he passed. He always had a single slice of toast covered with jam or marmalade with his breakfast. It's such a simple, common smell, but to this day (it's been almost 30yrs) it never fails to take me back and remind me of my grandfather, even if it's only for a split second before I have to continue with my day.

It's weird because I loved the smell of gasoline as a child and now I absolutely hate it. There was no psychological experience or anything that made me hate gas, just as I got older it smelled less good over time.

I love the smell of fresh asphalt or fresh tarred driveways and just figured out why. As a child I lived next to new construction and streets and so it smells like the innocence of childhood.

Remember the number one scientific rule about odors..... "He who smelt it, dealt it!!"

Stink bugs have an incredible defense. You only have to kill one to learn that you should not kill... at least by squashing.

New babies have a smell that I have heard people say they love. I think I heard they give off a scent that triggers certain chemicals in our brains meant to make us want to peotect and care for them.

Perfumers use the chemistry discussed in your video to create rain accords, water notes, and many others. Demeter makes single note fragrances including Grass, and one of my favorites, Dandelion, not normally a fragrance for perfumers. It's been fascinating to begin to understand the chemistry of fragrance and the basis of many accords/notes originating in Nature. Then there are all of Maison Margiela's "Replica" series of perfumes. They're meant to evoke a moment in real life. By The Fireside, Jazz Club, Whispers in the Library, are some of the themes.

My favorite section of the grocery store is the coffee aisle and my favorite specialty clothing store is a leather wear store. It isn't hard to figure out why.

I love the smell of the ocean. But for me, growing up near a working waterfront, the smell of the ocean is the sea itself, seaweed, fish (sometimes pungent) and diesel. I just spent my first winter in the Florida keys and I was surprised at just how faint the ocean smell is. Also there is a lot more life in Maine waters where the water a a deep green and scuba diving at times is like being in pea soup. Whereas the water in Florida is super clear.
