If you’ve got kids and spend any time scrolling parenting blogs or Instagram, you’ve probably come across ads for subscription boxes like KiwiCo. But lately, a new name has been popping up more and more: Tinkerer. Their boxes promise hands-on STEM and creative projects that kids can build, explore, and actually learn from—all while having fun.
I’d seen Tinkerer’s bright, clever projects online for months before I finally got my hands on them. My kids, ages 7 and 10, are endlessly curious but also hard to keep entertained beyond screens and LEGO. So when the chance came to try out a couple of Tinkerer Boxes, I was more than a little excited. The verdict? They were every bit as fun—and surprisingly touching—as I’d hoped.
What is Tinkerer?
Tinkerer is a subscription box designed to bring science, art, and engineering into kids’ everyday play. Each box comes packed with materials for a complete DIY project, plus an illustrated magazine that blends storytelling, comics, and real-world science. Unlike the “Pinterest project scramble,” everything is included—no last-minute trips to the craft store, no wondering if you’ve got the right glue.
The boxes are grouped by age and interest, so kids get activities tailored to their developmental stage:
- Wonder Box (Ages 3–5): Pretend play, sensory fun, and early learning.
- Odyssey Box (Ages 6–8): Hands-on STEM adventures like spy science, chain reactions, and water pianos.
- Explore Box (Ages 9–12): More advanced projects like pinball machines, projectors, and chemistry experiments.
Each kit is carefully designed so kids don’t just make something—they understand how it works.
How Does Tinkerer Work?
Tinkerer is a subscription service where a new box arrives every month, packed with projects to surprise and inspire your child. You can subscribe monthly or prepay for several months at a lower cost per box.
Right now, you can start with a trial box for just £14.99 with code ‘TRYSTEAM’.It’s a perfect way to see the magic for yourself without committing to the full subscription right away. My kids and I loved this—one affordable box that gave us an entire afternoon of fun and discovery.
What’s inside the Tinkerer Box?
Our first Tinkerer project was the Coin-Operated Capsule Machine, and it instantly became a favourite in our house. Inside the box were all the materials my kids needed to create their very own working machine:
- Pre-cut wooden pieces to build the machine
- Screws, rubber bands, and the clever mechanics that make it coin-operated
- A set of colourful capsules, ready to be filled
- Step-by-step illustrated instructions
- Tinkerer’s magazine with comics, games, and science explanations
The build itself took about an hour with both kids working together (ages 7 and 10). I helped with a couple of tricky snaps, but for the most part, they were able to follow the instructions themselves. The moment they dropped in the first coin and the capsule rolled out? Pure magic.
Can Kids Do Tinkerer Projects Without Help?
For the most part, yes. My 10-year-old could handle almost everything solo, while my 7-year-old needed a bit of guidance with scissors and tricky steps. But honestly, doing it together was half the fun.
If you want a completely independent activity for younger kids, you might need to step in at first. But if you’re looking for something that sparks connection as well as creativity, these boxes are perfect.
Why Kids Love It
The capsule machine is more than just a toy—it became part of my kids’ play for weeks. They loved refilling the capsules with little prizes, jokes, and even homemade coupons (“10 minutes extra screen time” was a big one).
It turned into pretend play too—suddenly our living room was an arcade, and my daughter was the “shopkeeper.” They even made tickets and kept score. It was wonderful to see them use the machine as a springboard for imaginative play.
And of course, they were learning the whole time—about levers, gears, and how coin mechanisms work—without it feeling like a lesson.
How Much Does Tinkerer Cost?
Tinkerer boxes typically range between £23–£27 per month, depending on the subscription length. Prepaid options save you a bit more, and considering each kit can easily fill an afternoon (plus get reused for weeks afterward), I found it a great value compared to toy-store impulse buys.
And if you’re curious but not ready to commit, you can try a trial box for just £14.99 with code ‘TRYSTEAM’. For less than the cost of a trip to the cinema, you’ll get a hands-on project that sparks hours of learning and play.
What Are Tinkerer Boxes Like in Real Life?
Honestly? Better than I expected. The packaging is kid-friendly without being wasteful, and the instructions are clear enough that my kids could mostly follow along themselves. I did lend a hand for trickier parts—like snapping tight wooden pieces into place—but I actually enjoyed helping.
The build process itself was a great bonding activity—no bickering, just teamwork (a rare gift!). And afterward, the capsule machine kept finding its way back into their play. Some toys get tossed aside after a day or two, but this one kept sparking new ideas.
One afternoon, my son filled all the capsules with riddles for his sister. Another time, they turned it into a “mystery chores” machine, where each capsule had a small household task inside. (Not going to lie, I may encourage more of that!)
It’s that mix of fun, creativity, and genuine learning that makes this box special.
Should You Sign Up for Tinkerer?
Absolutely. If you’ve ever wished for a rainy-day activity that feels meaningful, or if you want your kids to explore science and engineering in a way that doesn’t feel like homework, Tinkerer is a gem.
It’s educational, yes—but it’s also joyful, clever, and deeply satisfying for kids. My two are already asking when the next box will arrive.
And as a parent, I’ll admit: I’m secretly excited too.
Final word?
Tinkerer succeeds in sparking curiosity, building confidence, and creating memories that go far beyond the box.
