Little kids are incredibly impressionable. Their minds are still learning and growing, which is a prime opportunity to tell them facts that will absolutely blow their little minds.

Whether you’re a parent, an aunt or uncle, a cool older sibling, or another adult in their life, there are a few facts you can tell them that will make you seem like you know everything about the world.

If you want to impress a young person in your life, this list will give you facts of all sorts that may even blow your own mind.

A Redditor went to Ask Reddit to ask:

“What are some cool facts to tell a 5 year old?”

Take notes!

Watch them try to do the impossible.

“You can’t lick your elbow.”

“Then you get a good 5min watching them try.” ~ CriticallyNormal

“Nah you wanna tell them that you can. Then they’ll try for the whole day and get increasingly p*ssed off.” ~ harkat82

“Actually a lot of kids can lick their elbow. Since they’re younger and more flexible they can bend their arms in weird directions in order to lick their elbow.” ~ chickenugget814

“You’re absolutely right. I just tried it on my 6 y/o nephew and promised him that he could have my phone (he always wants to play games with it) if he could do it. So yeah, bye Reddit!” ~ ninjatoes36

If you’re happy and you know it.

“Astronomer here! Clap your hands once, and then clap them again a second later. The two claps were actually done about 30,000 miles apart thanks to the Earth’s motion in space!”

“I did the calculation once and interestingly most of the stuff you think of, like the rotating Earth or out orbit around the sun, is a negligible part of it. The real contributions are from our star orbiting the galaxy, and the galaxy’s motion itself in space.” ~ Andromeda321

“Is that the earth moving around the sun or the sun moving around the center of the galaxy? Hey, are we aware if galaxies are rotating around a central universal point?” ~ whohw

“The earth moving around the sun is much, much less distance at any moment than the distance we get from the sun orbiting the galaxy.”

“Galaxies do not orbit around a central point, but galaxies around us are heading in the direction of the ‘Great Attractor’ which is outside our visible universe. It’s probably just an even bigger group of galaxies.” ~ Andromeda321

A free, new pet.

“The ducks at the park are free, you can take them home.” ~ NotDaWaed

“I tried this last week. Park police were not too impressed.” ~ mavinochi

“I caught one when I was a kid! And that’s how I got bitten by an angry mama duck.” ~ ZarquonsFlatTire

“Gotta be careful with them ducks. Some belong in gangs n sh*t.” ~ mavinochi

The Pacific Ocean.

“Every ‘c’ in ‘Pacific Ocean’ is pronounced differently.” ~ UWYO-Agent-7

“I just repeated Pacific Ocean several times in a really exaggerated manner just to be sure.” ~ AnRudIsAnamh

“Just told my wife ‘every c in Pacific ocean is spelled differently’… Whoops.” ~ Curran919

Numbers are weird.

“There are numbers below zero.” ~ Sergeant_Dimitri

“And other numbers orthogonal to the real number line entirely.”

“You might have to explain exponents/squaring things but some kids are precocious.” ~ 7788445511220011

“Are those imaginary numbers?” ~ rushingkar

“Yes. There might even be more examples that I’m not aware of tbh, but that was what I was thinking about.” ~ 7788445511220011

“Yep, we can get weirder. Real number exist in a line, complex numbers exist in a plane, and quaternions exists within a volume.”

“So, there exists a range of numbers orthogonal to both the simply real numbers and the simply imaginary numbers. Numbers above zero, numbers below zero, numbers to either side zero, and … hmm, before and after? back and forth from?”

“I dunno, I’m already disoriented.” ~ Haven_Stranger

Advice for dealing with bullies.

“If your being chased by a bully, run until there right behind you then drop into a ball and they’ll trip over you.”

“Then kick ’em in the d*ck.” ~ Lucidpotato666

“Did this as a kid. It worked SO well like it was a movie or something. I can still see him in the air.” ~ Mission_Huckleberry

“Will he ever land?” ~ PurpleVein

“That must have been one hell of a kick in the d*ck.” ~ striped_frog

Our top teeth may or may not be immobile.

“You can’t move your upper teeth.” ~ SNOUMANN

“Some other person on here said my upper teeth are moving at 30,000 miles per second.”

“Get your stories straight reddit. ComeOn!” ~ vitium

“My 7 year old can move one of her upper teeth- it’s loose and we’re waiting for it to fall out.” ~ linuxgeekmama

“Canadian dentistry simply consists of taking part in a hockey match where the offending teeth can be smashed out of your face by a large stick.” ~ imagine_amusing_name

“You can if you have dentures :D” ~ sodapopzero

Put ’em all together and what do you got?

“A group of zebras is called a dazzle and a group of giraffes is called a journey.” ~ Magicbean96

“Don’t Stop Believin’ this.” ~ termiAurthur

“I thought a group of giraffes was called a Tower…” ~ MyCatsAreDumb

“Eiffel for that every time…” ~ PawnedPawn

Today’s yesterday is yesterday’s tomorrow.

“We will never experience tomorrow as by the time it’s ‘tomorrow,’ it will be today.” ~Redditor

“You can say this about right now. There is never a right now bc once you even say it or think about it, it’s gone.” ~ thedopestantelope

“I keep trying to explain to my almost five year old that no, it’s not tomorrow now.” ~ linuxgeekmama

“Easy: promise you’ll take him to the zoo (or Disneyland or whatever) tomorrow. Then, every day: ‘Are we going to the zoo today?’ ‘No, it’s today. I said we’d go tomorrow.’”

“Eventually, they’ll catch on: My parents don’t love me. Also, the concepts of today and tomorrow. The important things.” ~ theAlpacaLives

It’s all in what you eat.

“Flamingos get their pink colour from shrimp they eat.” ~ cthullu-and-the-maid

“But how many shrimps do you have to eat, to make your skin turn pink?” ~ greccojunior

“I have never eaten a shrimp and my skin is pink.” ~ diablorious

We tend to think we know it all.

But sometimes we are learning just as much as the little ones in our lives.

Truly, we do learn something new every day.
