Welcome to Brain Pop! — where your brain goes boom with one mind-blowing fact every day!
I’m your host, Fin — and today’s fact is loud, like really loud. So maybe cover your ears and hold onto your headphones, because we’re about to blast off into the world’s biggest BOOM ever recorded.

Let’s get that brain popping — with a BOOM you’ll never forget!

Alright, here it is:
The loudest sound that’s ever been measured on Earth was caused by a volcano — and not just any volcano, but Krakatoa in Indonesia, back in 1883. When it erupted, the explosion was so powerful, it created a sound wave that could be heard over 3,000 miles away — that’s around 4,800 kilometers!

To help you picture that:
•That’s like an explosion in New York being heard all the way in California.
•Or from London, England all the way to Egypt.
•Or from Sydney, Australia to Singapore.

Pretty far, right? And people that far away didn’t just hear a faint rumble — they heard a BOOM so loud, it was like it happened right next to them.

Scientists believe the sound reached around 310 decibels.

But wait — what’s a decibel, and how loud is that?

Here’s a quick sound-o-meter to help:
•A whisper is about 30 decibels.
•A normal conversation is around 60 decibels.
•A dog bark is about 90 decibels.
•A car horn? Around 110 decibels.
•A jet engine taking off? A super loud 140 decibels — and that can hurt your ears if you’re standing nearby!

But Krakatoa’s boom? It was so loud, it ruptured eardrums of sailors over 60 miles away and caused a pressure wave that circled the entire Earth four times.
Some people who were close to the eruption said they didn’t just hear it — they felt it in their chest.

It literally shook the air!

To put it in kid-size terms:
•It was louder than a thousand race cars revving at once.
•Louder than an entire marching band blasting in a small room.
•And louder than if every kid at a birthday party screamed at the same time… next to a volcano.

And get this: the eruption caused a giant tsunami, changed the weather, and even made sunsets look red and purple all around the world for months afterward!

So yeah — the loudest sound wasn’t a rock concert or a rocket. It was Mother Nature saying, “BOOM!”

Wow! — that fact really made my eardrums wiggle!

Come back tomorrow for another fact that’ll make some noise in your brain. And here’s your question of the day:
What’s the loudest sound you’ve ever heard? Was it thunder? A firework? Your little brother yelling “MOM!” from the other room?

Imagine fish fell out of the sky like rain. Now, sit back and hear Fin tell us how this actually happens in some countries around the world.

You can't be serious can you? Fish falling out the sky like rain? Impossible! Or is it?

Welcome to Brain Pop! — where your brain goes boom with one mind-blowing fact every day!
I’m your host, Fin — your fearless fact-chaser — and today’s episode is so strange, you might not believe it. I mean… can it really rain fish?

Let’s get that brain popping — and don’t forget your umbrella!

Okay, picture this: You’re standing outside after a storm. The sky is clearing, the ground is wet, and something plops down at your feet.
You look closer and—wait—is that a FISH?!

Believe it or not, there’s a place in the world where this actually happens — almost every year. It’s called Yoro, a town in Honduras, in Central America. But did you know there’s also been reports of this happening in parts of the world, too!

It’s called a “fish rain”, and it’s not magic — it’s science. Sort of weird, windy science.

Here’s how scientists think it works: Sometimes, during strong thunderstorms or even tornadoes over water, small fish get sucked up from lakes or rivers by spinning winds. Think of it like a big vacuum cleaner in the sky. The fish get pulled high into the clouds, swirl around, and then—when the storm moves over land—they fall back down, just like raindrops. SPLAT!

Most of the time, it’s little fish — not whales or sharks (phew!) — and sometimes the fish are still alive when they land! People in these towns have even collected them in buckets and cooked them for dinner. Instant fish delivery? Sort of!

And while fish rain is rare, it’s not the only weird weather we’ve seen on Earth. There have been stories of it raining frogs, worms, and even spiders in some places!
Nature is weird. And we love it.

Wow — from the sky to the skillet, this fact really made a splash!
Thanks for popping your brain with me on today’s totally fishy episode of Brain Pop!.

Join me tomorrow for another strange-but-true fact. And here’s your big question for today:
If you could make it rain anything, what would it be? Gummy bears? Pillows? Chocolate coins? Maybe… money?

See you next time on Brain Pop! — where curiosity is cool, facts are fun, and every day your brain goes BOOM!

In today's episode Fin tells us about an animal that sleeps for 3 years.

That's THREE YEARS!!!!.

Can you believe it? Find out if this animal is just lazy or if it has a very good reason for taking such long naps.

Your mind will be blown. BOOM!

Welcome to Brain Pop! — where your brain goes boom with one mind-blowing fact every day!

I’m your host, Fin — your fact-loving friend who’s always curious, always learning, and sometimes a little bit sleepy. And today’s fact? It’s all about one very slow, very snoozy animal.

Let’s get that brain popping — and maybe grab a pillow just in case!

Did you know that some snails can sleep for up to 3 years?

Yes, you heard that right — three whole years! That’s 1,095 days of nap time. That’s longer than kindergarten, first grade, and second grade put together. And it’s not just a power nap… it’s serious sleep.

But why would a snail do that?

Well, some snails live in places that get really dry or really cold — and snails need moisture to survive. So when the weather turns tough, certain snails curl up in their shells and go into a super deep sleep called hibernation or aestivation (that’s like hibernation, but for hot or dry conditions). It’s their way of pressing pause until the world outside is safe again.

Now, humans? We definitely don’t sleep that much. Most kids need about 9 to 12 hours of sleep every night — just enough to rest, recharge, and grow. And even though it feels like we could sleep for 3 years sometimes (especially on Monday mornings!), that’s nothing compared to our sleepy snail friend.

And snails aren’t the only long snoozers in the animal kingdom!
Check these out:
•Bears hibernate in the winter for 5 to 7 months, living off their fat stores while they rest in cozy dens.
•Groundhogs can hibernate for up to 150 days — that’s like snoozing through the entire school year!
•Alpine marmots (they’re kind of like mountain squirrels) sleep nearly 9 months a year. That’s more sleep than wake time!

Hibernation is a special trick animals use to survive harsh seasons without food or warmth. Their body temperature drops, their heart slows down, and they hardly move at all. It’s like hitting the ultimate snooze button.

So next time someone tells you you’re being lazy… just say, “Hey, I’m going full snail mode!”

Phew! I think my brain just took a nap from learning all that.
Thanks for popping your brain with me, Fin, on today’s slow and sleepy episode of Brain Pop!.

Come back tomorrow for a fact that’ll wake you right back up! And here’s your dreamy question of the day:
If you could hibernate for a season — which one would you sleep through, and why? Winter snowstorms? Summer heat waves? Or maybe just Mondays?
