Monthly hands-on kits, pen pals worldwide, experiments, recipes, magic tricks. Kid‑owned, age 7.
Two minutes. Monthly or Annual. Pen pal postcards from day one. Cancel anytime.
Book-sized kit lands in the mailbox. Pop it open and the lab unfolds. When you're done, fold it flat and slide it on the shelf.
Do the experiment, eat the recipe, write back to your pen pal, and post your video with #PopSciFun.
Every kit is a hands-on lesson kids can build, test, and keep. Ships flat, pops open, turns learning into play, then folds back to the size of a book and slides right onto the shelf. Screen-free fun the whole family enjoys together. What's inside changes every month. The point isn't a checklist of parts. The point is kids begging to open the next one.
Ships flat. Pops open into a hands-on lesson kids can build, test, and keep. Folds back down to the size of a book for the shelf so a year of science fits on one row.
Hands-on. Weird. Memorable. The way Caleb wishes science was taught at school. Kids finish the kit and teach the lesson back to you.
The one thing in every single kit. A handwritten card from another Young Scientist Club member. Could be Ohio. Could be Osaka. We shuffle by hand.
One month a chemistry experiment, the next a build challenge, the next a magic trick with real science under the hood. Surprise is half the fun.
Kids are happy to read and experiment when the experience is enjoyable, and that's what PopSciFun does best. Make Science Fun.
Send one as a birthday or holiday gift and watch it steal the show. A present grandparents can feel great about, because their grandkid is learning real science while having a blast.
Every plan includes the monthly kit and a pen pal postcard. Kids learn through play, excited and surprised every time a kit pops open. What's inside changes every month, that's the point.

Every annual subscription funds five PopSciFun kits for kids in communities that need them most. That's not a marketing line. It's math. We buy the kits, we ship them, we send you proof.
Scholarship kits are funded from annual subscription revenue. Not tax‑deductible - PopSciFun is not a 501(c)(3). Partner schools announced as onboarded.
Every kit includes a blank postcard addressed to PopSciFun HQ. Kids add their own stamp, write something, and mail it in. Every postcard we get is shuffled and slipped into another kid's next kit. No kid ever sees another kid's address.
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.
Homeschooled. Age 7 1/2. Loves Legos, origami, robots, and anything that fizzes. His goal: teach 1 million kids that science is fun through the Young Scientist Club, one monthly kit at a time.
I'm Caleb's dad. During the day I serve as a University Director of Innovation and Intellectual Property. After work I enjoy making my kids healthy food, teaching them about fitness, and most importantly, science. Recently Caleb and I decided to start a business - not a lemonade stand, an actual company.
"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."
Explosive science kits. Pen pals worldwide. Scholarship kits funded. A community that tells every kid: you belong here.
