People Share 85 Facts To Tell A 5-Year-Old That Will Blow Their Mind

When I first heard that there are more stars than there are grains of sand on all beaches in the world, I went on a mission to count all the grains out there to see if it’s true. Needless to say, “the world” was the size of my yard and I was five or so. You see where I’m going.

The truth is, kids are naturally curious and always ready to soak up the info they cannot entirely grasp. Tell ‘em about the Bermuda Triangle, and I guarantee they will be pulling all-nighters to solve the biggest puzzle on the planet.

So when one Redditor posted the question “What are some cool facts to tell a 5-year-old?” on r/AskReddit, people rolled up their sleeves. 1,400 comments later, the replies are in, and honestly, some of these may work on adults too.

Kids are naturally curious as they have that thirst for exploring how things work in life. No wonder some of these hard-to-believe facts can seriously blow their minds.

It turns out that not only is being curious a valuable trait on its own, it also contributes to academic achievement. This research has shown that cultivation of curiosity in children is linked to later aptitude in science. And this 2018 study has shown that the more curious the child, the more likely they may be to perform better in school—regardless of economic background—as suggested by a new study published in Pediatric Research.

Susan Engel, a developmental psychologist at Harvard University and the author of The Hungry Mind: The Origins of Curiosity in Childhood, said that many teachers circle curiosity as the most important quality in a list for students to acquire in school.

However, it’s no secret that as a child grows, they become increasingly less curious in finding out all the things and less prone to ask questions. Susan explains this gap between intense curiosity and apparent lack of it in older kids as a “a by-product of that child’s increased knowledge.”

“And if curiosity is, as psychologists say, the urge to explain the unexpected, then as more of everyday life becomes familiar, a child might encounter fewer unexpected objects and events.” That’s why 7-year-olds exhibit way less of it than when they were younger.

Meanwhile, author Elizabeth Gilbert suggests that curiosity is key to a creative life. She explains: “leading a creative life is to believe that there’s a reason that you’re into this thing, whatever it is.” And the only way to find out what that reason is is “to look a little closer.”

This is where your sense of curiosity comes into play. If you’re genuinely interested in explaining the unexplained, discovering the undiscovered, and finding answers even where there are none, you are likely on a good track.

There’s a disease know as Münchmeyer’s disease, wherein the afflicted’s damaged muscle tissue is ‘healed’ with skeleton tissue, eventually culminating in the afflicted’s muscle system being converted into a secondary skeletal system, hence it’s a common name, second skeleton disease. It’s completely incurable and largely untreatable. & since it symptoms usually don’t appear until the age of 10, you could have it & we wouldn’t know for another 5 years.
Thanks to a couple of quantum mechanical things that most adults would have problems comprehending, let alone a 5-year-old, it’s entirely possible for what’s know as a ‘hard vacuum’ (a place where no matter can exist) to spontaneously form anywhere in the universe. Once formed, it would propagate at lightspeed until it destroyed all matter in the universe

Sharks don’t actually like eating people (we apparently taste bad to them), that’s why most shark bites stop there. Most sharks bite people out of curiosity or because the person unwittingly provoked the shark

A lot of dinosaurs had feathers, and birds are descended from dinosaurs. Because hair and feathers break down much more easily than bones, it’s possible many dinosaurs had fur/feathers, but because all that remains of them are bones, archaeologists can only speculate what they looked like. There’s a very interesting post talking about this somewhere on the internet, I recommend looking it up. According to that post, our modern conception and depictions of dinosaurs is like if scientists in the future tried to recreate the dogs and cats of today based solely on their bones, without any fur.
