What's in every box

The Mystery Curriculum.
Six things. Every month.

Kids don't know what's coming, but each month connects to the next. By month 12 they've touched chemistry, physics, biology, earth science, and engineering — hands‑on.

🧪

Real Experiment

Part of our rotating Mystery Curriculum. A new science concept every month — chemistry, physics, biology, you name it.

✉️

Pen Pal Postcard

A handwritten card from another Young Scientist Club member. Could be Ohio. Could be Osaka. We shuffle by hand.

🥞

Kid‑Friendly Recipe

Tied to that month's science theme. When we do gas laws, you're eating pancakes.

✨

Magic or Prank

A trick that makes grandma believe in magic for four seconds. Real science under the hood.

💪

Physical Challenge

Because science kids need to move, too. A new movement mission every month.

🎁

Surprise Bonus

Stickers, posters, patches, tools. Caleb picks them. Dad isn't allowed to tell you what's inside.

The mission

1 Annual Plan

Scholarship kits are funded from annual subscription revenue. Not tax‑deductible — PopSciFun is not a 501(c)(3). Partner schools announced as onboarded.

"Dad, if kids can't afford a kit we should just send them one. That's not hard. We just have to sell more kits."

Your pen pal is waiting.

The postcard format removes all social pressure. No face‑to‑face. Just science, shared curiosity, and connection at their own pace. Thoughtfully designed for every kid — including kids on the autism spectrum or anyone who learns differently.

"When a postcard comes I run to the mailbox. Every time. I can't help it."
— Caleb, age 7

Kid‑owned. Parent‑operated.

Caleb S.
Founder · Chief Scientist · Age 7

Homeschooled. Loves Legos, origami, robots, and anything that fizzes. He couldn't find other kids who loved the same things, so he decided to build a club that arrives in the mail.

"I made PopSciFun because I want every kid to love science the way I do. Even the kids whose schools don't have a science lab. Especially those kids."
Dad
Co‑Founder · Handles the grown‑up stuff

I'm Caleb's dad. Last year he decided he wanted to start a company — not a lemonade stand, an actual company. So we built one together. He picks the experiments. I handle the shipping, the taxes, and the late‑night packaging sessions.

"Every annual subscription funds five free kits. That's the whole reason we exist. Caleb picked the number."
"I want to meet 1 million kids who love science. That's why I stay up late thinking about this stuff even when Mom says go to bed."
— Caleb, age 7
What families say

Early reviews
from the Young Scientist Club.

★★★★★

"Best gift I have ever given my grandkids! PopSciFun is amazing from the first moment. The fact that it's built by a 7‑year‑old makes it even more special. Caleb gets kids in a way that big company kits do not."

Susan
Parent & Grandparent · Annual Subscriber
★★★★★

"My son actually runs to the mailbox now. The pen pal postcard is genius — he writes on his own time and a new friend writes back. It feels personal, not corporate."

Maria T.
Homeschool parent
Alpha tester
★★★★★

"We cancelled two other subscription boxes and kept PopSciFun. The Mystery Curriculum actually teaches something. And the recipe card got my picky eater to try pancakes because he wanted to see the gas law in action."

Devon R.
Parent of two · Monthly
Alpha tester
★★★★★

"Our robotics club bought a bundle. The kids fought over who got to open the tab. That's when I knew it was different — it's theirs, not mine."

Frequently asked

Questions we get
all the time.

✉️How does the pen pal postcard work?
Your kit includes a pre‑stamped postcard addressed to PopSciFun HQ. Fill it out and drop it in any mailbox. Or submit answers at popscifun.com/penpal. We shuffle all postcards and slip one into a random member's next kit. No matching, no databases, no home addresses shared.
💥What's actually in an Explosive Science Kit?
Six things. A real experiment from our Mystery Curriculum, a handwritten pen pal postcard, a kid‑friendly recipe tied to the science theme, a magic trick or prank, a physical challenge, and a surprise bonus Caleb picks himself.
📦When do kits ship?
The first kits ship the week of July 4, 2026. Order during presale to lock in the presale price ($24.99 monthly, $279.99 annual with code FOUNDER20).
💎What's the scholarship program?
Every annual subscription funds 5 free PopSciFun kits for kids in communities that need them most. We buy the kits from the annual subscription revenue, ship them to partner schools and programs, and publish proof on the scholarship page. Not tax‑deductible — we're not a 501(c)(3).
🏠Is this good for homeschoolers?
Built by a homeschooled 7‑year‑old for curious kids everywhere. Maximum education per kit, science resources, and global pen pals for kids who want connection beyond their immediate community. Use code HOMESCHOOL10 for 10% off.
💙Is PopSciFun good for kids on the autism spectrum or who learn differently?
Thoughtfully designed for every curious kid, including those who learn differently or are on the autism spectrum. The pen pal postcard creates real connection entirely on the child's own terms — no pressure, no scheduled calls, no social performance required. Kids share their results, recipes, jokes, and riddles in writing, at their own pace. The Young Scientist Club accepts every curious kid.
📬Can I order for a group or school?
Yes. Email learn@popscifun.com for bulk pricing. Science clubs, classrooms, robotics teams, homeschool co‑ops, science centers, and libraries — we love supporting groups of curious kids.
🔄Can I cancel?
Yes, cancel any time with one click from your Stripe receipt or by emailing us. No lock‑in, no phone calls, no "are you sure?" pop‑ups.
