Build your own wearable robotic hand that you operate with your own fingers with Thames & Kosmos Mega Cyborg Hand STEM Experiment Kit! The set includes 203 pieces to assemble a 16-inch robotic hand with mechanical fingers and amazing gripping capabilities. If you're also a fan of Marvel Cinematic Universe movies, imagine this as your very own Infinity Gauntlet! It also slips onto your own hand like a glove! What's great about this cyborg hand is that you don't need motors or batteries - just the power of air pressure, water, and your own hands! It's also adjustable for different-sized hands and easily re-configured for right- and left-handed users. During assembly, you'll also learn hydraulic and pneumatic systems in the real world!
