Mia’s Question Why does Dad cry when he cuts onions? Made for Mia, age seven
This book was made for Mia with love from Grandma October 2026 One of one. There is no other copy in the world.
Dear Mia, You asked your dad why he cries when he cuts onions, and he had no idea. I love that about you. Never stop asking. One day you will know things none of us do. With love, Grandma
One Tuesday evening, Mia asked “Why does Dad cry when he cuts onions?” It was a very good question.
Dad wasn’t sad. He was making soup. He was even laughing. But his eyes were pink and tears ran down his face. “It’s not me,” he said. “It’s the onion.”
“But why?” asked Mia. Dad put down the knife and thought about it. “You know what?” he said. “I have no idea.” A grown-up didn’t know! What’s your guess, Mia?
Clue one: a whole onion does nothing. Mia sniffed one. No sting. No tears. So the trouble only starts when the knife goes in.
Clue two: it floats. Dad tried goggles and looked ridiculous. Chemists have a better trick: a fan that blows the air away from your face. So the sting must be floating through the air.
An onion is full of tiny rooms. Two ingredients are kept apart in them. Cutting breaks the walls, and the two rush together.
Then a tiny helper makes a gas. The gas floats up and stings Dad’s eyes, so they make tears to wash it away. They weren’t crying. They were washing!
Dad didn’t know this either. Garlic has no helper, so garlic makes no one cry. And scientists filmed onions being cut: a sharp knife, going slowly, sprays far less. Dad went to sharpen his knife.
Mia’s experiment Next time a grown-up cooks, stand one step back and watch. (Grown-ups do the cutting!) Tears? Yes No Onion Garlic Was your guess right?
Mia called Grandma right away. She told her everything: the tiny rooms, the helper, the gas. The phone went quiet. “Well,” said Grandma, “I’ve cut onions for sixty years, and nobody ever told me that.”
Stump your grown-up! Why doesn’t a whole onion make you cry? Why doesn’t garlic make you cry? Which means fewer tears: a sharp knife or a dull one? Score: out of 3. You already know the answers.

Begin their bookCurious “why” and “how” questions about animals, the body, food, weather, space, everyday things. We don’t take questions about health worries, news events or anything we can’t answer kindly and truthfully. We’ll suggest a close question instead.
Think back to the last thing they wouldn’t stop asking about, or ask their parents quietly. Can’t find one? Tell us what they love, and we’ll send you a few questions to choose from.
A photo is optional: you can describe them instead. For the question, ask their parents quietly. No question yet? Tell us what they love, and we’ll suggest a few.
No. Without one, you can describe them instead, and the first page can hold your message alone.
We use them only to make this book. Their character is drawn with Google Gemini’s paid service, so the photo passes through it. A photo you choose only for the page with your letter never goes to any AI tool. We ask for a first name only. We delete the photos you sent within 7 days of delivery and your answers within 30 days. The finished book, with the photo beside your letter, stays on your page and at its gift link until you ask us to remove it.
No. Under Google’s terms for Gemini’s paid service, which is what we draw with, what we send isn’t used to train its AI or improve its products. Google keeps it only for a limited time, for example to catch misuse, and then removes it. Details are in our Privacy Policy.
Our design team directs the AI that makes the illustrations, then edits the book. The three character drawings come straight from the AI tool, so you’re the first to see them. Then our team looks over every page of the book and checks every fact before you see it.
No, it’s digital: a PDF and an EPUB. Read it together on a tablet, or print the PDF at home or at a local print shop.
When you read it first, you can change the title, their name and your letter. The name under your letter comes from the “From” name on your form, printed as you wrote it, so please check it there. If anything else is wrong, a typo in that name included, tell us on the same page and we’ll fix it for free.
Stripe processes our payments through its Link service, so your receipt and statement may show that name.
