A robot chameleon that won Educational Toy of the Year, a desk vacuum you build yourself, a microscope with a screen and lettuce you grow without dirt. Here’s what’s new from the Providence science-kit maker, and who each kit is really for.

Disclosure: This is free editorial. Thames & Kosmos did not pay for this coverage, and no samples were provided. We have not play-tested these products. This spotlight is built from the maker’s own pages, Amazon listings, The Toy Foundation’s awards page and the public sources listed at the end.
Some STEM toys are a worksheet in a box. Thames & Kosmos kits are usually the other kind: you build something real, it moves or grows or glows, and the science sneaks in while nobody’s looking. We went through the company’s 2026 releases on its own website and picked five kits for ages 8 and up, plus one showpiece anniversary build. Each one has the age grade, the safety warnings, a dated Amazon price, its highlights and what to know before you buy.
Meet the Maker
Thames & Kosmos was founded in 2001, when a Rhode Island science museum director and her son teamed up with a German publishing house that is about 200 years old. That’s the company’s own story on its Amazon brand page. Its U.S. office is in Providence, R.I. Its first product, it says, was a fuel cell car kit, and 2026 brings a 25th-anniversary hydrogen truck.
Today the catalog runs well past chemistry sets: robotics, physics, biology, Gecko Run marble runs, Spy Labs detective gear, and Kosmos family games such as EXIT and The Crew. The company says it wants kids and families to “think deeper, play longer, and figure stuff out.” Its 2026 releases show it. Many are build-it-yourself kits with thick illustrated manuals, the kind of toy that keeps a kid busy for an afternoon and then keeps working afterward.
Age grade: 8–12 years (Amazon listing; the maker says ages 8+ with adult help, 12+ on their own) · 133 pieces · 48-page manual · 3 play modes
Safety: CHOKING HAZARD: small parts, not for children under 3. The listing also warns it is only for children over 8 because of accessible electronic components. Needs 4 AAA batteries.
Kid Hook
You build a 15-inch robot chameleon that really walks, changes color to match what it’s standing on and shoots out its tongue at “snacks.” Then you program it by showing it colored action cards. No tablet, no app, just a lizard that does what the cards say.

Kid Hook
Build a little robot vacuum that sucks up crumbs, lint and dust from your desk all by itself. Mechanical feelers stop it from driving off the edge, and its face changes from happy to confused when it bumps into something. It’s basically a pet that does chores.

Kid Hook
First you build a space-capsule maze shaped like a ball. Then you twist the handles and thumb wheels to steer a metal marble through three swappable modules into the “Mission Capsule.” Drop it and you start again. It’s a puzzle you built yourself, which makes beating it extra sweet.
Good to know

Kid Hook
Put a bug wing, a hair or a leaf under the lens and see it big on a built-in screen, with no squinting through an eyepiece. It takes photos and 1080p video onto a microSD card, so kids can show everyone the gross stuff they found.

Kid Hook
Grow three kinds of salad greens with no soil and no watering can. Cotton wicks pull water up to the seeds inside a mini greenhouse, and when the greens are ready you can eat your science project. Bonus: there’s a real chance your kid will eat a salad they grew.
Good to know

Setup: no soil and no batteries. It needs a sunny windowsill and a few minutes of checking each week.

Thames & Kosmos says its very first product was the Fuel Cell Car & Experiment Kit, first sold in 2001. This 25th-anniversary truck splits water into hydrogen and oxygen, then turns them back into electricity to drive across the floor. It can also run on 2 AA batteries for a side-by-side comparison. Ages 10+, 30 pieces, 5 experiments (maker). $179.95 on thamesandkosmos.com, where it was listed as available on Oct. 26 but still tagged pre-order. We found no matching Amazon listing. We couldn’t see the box warnings online, so read the manual’s safety page before the first run.
If you buy one Thames & Kosmos kit this year, make it the Coding Chameleon. It’s the award winner, it’s screen-free, and at our check Amazon had it for less than half its list price. For the kid who likes gadgets with a job, Dusty is the fun pick. Orbital Maze is the one the whole family will fight over. The Digital Microscope suits a curious kid who has given up on eyepieces, and Hydroponics Lab is the cheapest way in. Every kit here is graded 8 and up and contains small parts, and each card above lists the batteries it needs.
Safety check: On Oct. 26, 2026 we scanned the full CPSC recall database (saferproducts.gov, 10,058 recall records, the newest dated Oct. 22, 2026) for “Thames” and “Kosmos.” We found no recalls naming Thames & Kosmos or any product in this spotlight.
