Brand new, open box item. The box may have some damage but the item is unaffected.

Discover hands-on engineering fun with the Thames & Kosmos Mega Cyborg Hand Hydraulic STEM Kit. This innovative kit lets kids build a wearable mechanical hand that moves using air pressure and water—no motors or batteries required. Once assembled, hydraulic pistons power each finger, allowing the hand to open, close, and grip objects with surprising strength and precision. Adjustable joints and multiple configurations make it customizable for different users, while the included learning experience introduces real-world applications of pneumatic and hydraulic systems used in robotics and industry.

• BUILD A WEARABLE MECHANICAL HAND: Construct a fully functional cyborg hand that fits over your own and moves with your fingers.
• HYDRAULIC POWER SYSTEM: Uses air pressure and water to operate pistons—no batteries or motors needed.
• REALISTIC GRIPPING ACTION: Adjustable finger joints provide precise movement and enough strength to lift objects.
• THREE CONFIGURATIONS: Can be assembled as a right hand, left hand, or claw-style design to suit different preferences.
• HANDS-ON STEM LEARNING: Teaches the principles of hydraulic and pneumatic systems used in industrial robotics.
• AWARD-WINNING KIT: Recognized as a STEAM Toy of the Year for inspiring creativity and engineering exploration.
