Thames & Kosmos Mega Cyborg Hand STEM Kit | Giant Hydraulic Hand for Pneumatic Learning

Experience hydraulics with a wearable mechanical hand

Thames and Kosmos invites curious builders to explore hydraulic and pneumatic principles through a giant, water powered hand. This hands on kit uses over 200 plastic pieces and piston tubes that you fill with water to create movement. No motors or batteries are required, relying on air pressure and water to power the finger action for a tactile learning experience.

Once assembled, the hand slips onto your own hand like a glove, allowing you to control the mechanical digits with your fingers. The fingers open and close with precise motion and can grip a range of lightweight items, from bottles to pencils. The grip strength and finger angles are adjustable, letting you experiment with different objects and tasks to observe how hydraulics translate human input into machine movement.

Three configurations for flexible use

• Right hand configuration
• Left hand configuration
• Claw like configuration for pinching and multi direction grip

With the thumb centered and each finger joint adjustable, the hand can adapt to different hand sizes. This versatility makes it easy to tailor your build for the items you want to lift and the motions you wish to explore.

Built to teach and empower

• 40 page full color manual with model building steps and science explanations
• Over 200 plastic pieces and piston tubes to assemble a functional hydraulic system
• Clear introduction to how pneumatic and hydraulic systems are used in industry

In addition to the hands on build, the kit acts as an approachable gateway to engineering concepts behind robotics and automation. You are encouraged to observe, compare configurations, and draw connections between real world machines and the working hand in your palm.

Award winning and practical

The Mega Cyborg Hand earned recognition as a STEAM Toy of the Year award winner by The Toy Association in 2021, underscoring its engaging approach to science and engineering. While outcomes may vary, users often report a satisfying sense of discovery as they test new materials and grip techniques.

Designed for home use, classrooms, and STEM clubs, this kit blends a wearable form factor with a straightforward hydraulic system. The no battery requirement, combined with a thorough manual, offers a tactile path into hydraulics and pneumatics while sparking curiosity about how such systems power real world robots and manufacturing tasks.
