He Reaches For It, Not the iPad
"I did not make him do it. He just started picking this up in the twenty minutes he would normally be on a screen."

100,000 Whys: The Science Comic for Curious Kids
Two pages a day, and your child grows up understanding how the world actually works, from why the sky is blue to why we get hiccups.
- 🌍
They'll know things most kids don't. Why volcanoes erupt, why ice floats, how you read a tree's age from its rings.
- 💡
Explains why it happens, not just that it does. That's the difference between remembering facts and thinking like a scientist.
- 🔍
Answers the questions kids actually ask, about everything: weather, animals, space, machines, food, their own bodies.
- 📚
Told in full-colour comics, so it gets read. Two pages a day is enough.

"He answered a question at dinner that I didn't know the answer to. He's eight. That was worth the money on its own."

"I've bought three science books for her and they all sat on the shelf. This one is a comic, so she actually reads it."

"He used to ask me why about forty times a day and I ran out of answers years ago. Now he goes and looks it up himself."

What's Inside
The questions children actually ask, answered in full-colour comics. Weather, space, animals, plants, machines, food, materials and the human body. Each entry shows what happens and then explains why it happens, so your child ends up understanding the reason rather than memorising the fact.
How Kids Use It
Two pages a day is enough. Every question stands alone, so there is no order to follow and nothing to fall behind on. Some children work through it front to back, others jump straight to whatever they are curious about that week. Both work.
Shipping
Dispatched within 1 to 2 business days with tracking emailed as soon as it ships. Free shipping on all orders.
Return Policy

He corrected me at dinner
He explained why the moon looks bigger near the horizon. I had no idea. He's eight and he'd read it that morning.
The first one he actually reads
I've bought three science books and they all died on the shelf. This one is a comic, so he picks it up without being told.
I stopped saying I don't know
He used to ask why about forty times a day. Now he goes and finds it himself, then comes back and tells me.
It replaced 20 minutes of iPad
Not because I made him. He just started reaching for it instead.
It explains the why, not just the fact
Most kids' science books give you the answer. This one shows the reason underneath it, which is the part that actually sticks.
She doesn't like reading. She likes this.
The pictures carry the explanation, so she gets through a page without it feeling like work.
Whatever she's obsessed with this week, it's in there
Volcanoes one month, the human body the next. One book has covered all of it.
He is still using it!
Two pages a day and we're still finding things we haven't read. Cheapest thing I've bought him.
Not a Fact. An Explanation.
Anyone can tell a child that hot air rises or that the moon causes tides. The difference here is that every answer shows the reason underneath it, drawn out step by step until it makes sense on its own.
That is what the cover means by a scientist's way of thinking. Your child stops collecting facts and starts working things out, which is the part that carries into everything else they learn.
💡 Two pages a day. They will be explaining it back to you by the weekend.
The Questions You Ran Out Of Answers For
Why can't we see the stars in the daytime. Why does a plane taxi before it takes off. Why is the sea salty but rain isn't. Why do we get hiccups. Why does ice float when almost nothing else does.
Children ask about forty of these a day and most of us get through three before reaching for a phone. This is the book they can go to instead, and come back with the answer themselves.
🔭 Weather, space, animals, plants, machines, food and the human body, all in one place.
Not a book of facts. A book that shows them why.
Every answer works through the reason underneath it, step by step, so your child ends up understanding how it happens rather than memorising that it does.

James W.Frequently Asked Questions
?What's actually on a page?
Each question gets a full-colour comic. The characters walk through what is happening and why, step by step, so the explanation is drawn rather than described. It is closer to a graphic novel than to a reference book with a diagram in the corner.
?My child doesn't like reading. Will they use this?
This is the question we are asked most. Because everything is told in comics, a child follows what is going on before they read a word, and every question stands alone so there is no chapter to commit to. Most parents tell us this is the first science book their child picked up without being asked.
?What ages is this right for?
It reads at two depths. A younger child follows the pictures and gets the idea. An older one reads the full explanation underneath and understands the mechanism. The same book stays useful for years rather than being outgrown in a season.
?What does it actually cover?
The questions children genuinely ask, across weather, space, animals, plants, machines, food, materials and the human body. Why we cannot see stars in the daytime. Why a plane taxis before take-off. Why ice floats. Why we get hiccups. Why the sea is salty when rain is not.
?Why not just look it up online?
A search gives one answer and closes, usually written for adults, and it means handing a child a screen with everything else on it. This sits on the shelf, needs nobody's permission, and gives the reason underneath the answer rather than just the answer.
?How do we use it day to day?
Two pages a day is enough. There is no order and no schedule, so some children work through it front to back while others jump straight to whatever they are curious about that week. Both work.
?Is it tied to a school curriculum?
No. It is general science written for curiosity rather than for a syllabus, which is why children read it for fun. It sits alongside school work rather than repeating it.
?Shipping and returns?
Orders are dispatched within 1 to 2 business days with tracking emailed as soon as they ship. Free shipping on all orders. You also have 30 days from delivery. If it is not right for your child, contact us for a full refund.
