This wearable mechanical hand kit allows users to assemble and operate a functional robotic hand using their own fingers. The system operates without motors or batteries, relying instead on air pressure and water hydraulics to power the movements. Hydraulic pistons enable the mechanical fingers to open, close, and grip objects with sufficient force for lifting. Each finger joint can be individually adjusted for precise positioning and movement control. The kit offers three configuration options: right hand, left hand, or claw-like setup, with adjustable sizing to accommodate most hand sizes. Through assembly and operation, users gain practical understanding of pneumatic and hydraulic systems, similar to those used in industrial robotics applications such as automotive manufacturing. This product was recognized as the 2021 STEAM Toy of the Year by The Toy Association.

A Gecko Run marble run that sticks to whiteboards, doors, windows and other smooth surfaces with nano-adhesive pads, so it can build height with fewer pieces. The STEM edition teaches physics concepts such as potential and kinetic energy, momentum and centripetal force.

A cooperative escape-room card game from the EXIT series. Players work together to find the missing sheriff of the frontier town of Fortune City. They choose the order of locations to search and the townspeople to question, and collect clues along the way.

Kids' binoculars with large, chunky parts, adjustable width, soft eyecups and a focus wheel. The kit adds a specimen box and compass that clip onto the strap, plus stickers. It's tied to the Wow in the World podcast, with exclusive audio for a guided nature scavenger hunt.

A build-it-yourself 3D marble maze with a space theme from Thames & Kosmos. You build three modules that click into a spherical base, then use two handles with thumb wheels to tilt and rotate the maze and guide a marble to the Mission Capsule. The modules can be swapped for new challenges. Listed as coming soon or pre-order.

A Thames & Kosmos kit for building a model truck that runs on a hydrogen fuel cell. You add water, the fuel cell splits it into hydrogen and oxygen, and the same cell then combines the gases to make electricity that drives the truck. Listed on the maker's site as coming soon or pre-order.

KICKSTART YOUR ASTRONOMY ADVENTURE: This high-quality, durable refractor telescope is perfect for young scientists starting their observations of the moon, stars, planets, and wows in the sky! DETAILS & SPECS: This beginner scope features two eyepieces for 25x and 50x magnification, a focus knob, and an altitude adjustment handle. It also comes with a sturdy aluminum tripod with adjustable legs (can extend up to 48 inches) to keep your telescope steady during your observations. LEARN ABOUT & OBSERVE THE WOWS IN THE SKY: The 8-page, illustrated “Wow-To Guide” explains to kids (and their grownups!) how the telescope works, and what to look for in the night sky–examine the Moon’s craters, planets like Mars, Jupiter, and Saturn, and identify specific stars and constellations. BONUS SCIENCE TOOL: This kit comes with a star wheel so that kids can determine what stars and constellations to look out for at any given date and time in the Northern Hemisphere! EXCLUSIVE AUDIO CONTENT: The #1 family science podcast “Wow in the World” hosts Guy Raz & Mindy Thomas transform this classic scientific instrument into a unique, multi-sensory experience: tune into the audio “Wow Facts” that await you, accessible only within the pages of the “Wow-To Guide!”

A Thames & Kosmos rock tumbler that turns rough stones into polished rocks while teaching erosion, weathering and the rock cycle. It comes with natural rock samples, including tiger's eye, aventurine and rose quartz, plus four polishing grits and jewelry settings for making accessories.

A Thames & Kosmos kit for building a race car powered only by compressed air. An integrated pump fills the tank, and the air-powered piston engine works like a combustion engine without burning fuel.
