Description

Explore hydraulics, pneumatics, and robotics with your very own GIANT hydraulic hand! Using over 200 plastic pieces and piston tubes that you fill with water, build an awesome mechanical hand that uses hydraulic power to simulate the movements of the human hand no motors or electricity required! Once assembled, your cyborg hand slips onto your own hand like a glove, with mechanical fingers that you operate with your own fingers and that can grip objects with enough force to lift them. Challenge yourself to pick up and hold a variety of items like bottles, pencils, small items anything with reach! The hand can be configured in three ways left hand, right hand, and claw-like, with the thumb in the center and can be adjusted to fit virtually all hand sizes. A 40-page, full-color manual guides model building and experimentation and provides engaging scientific information about how pneumatic and hydraulic systems are used in industrial robots to assist with a variety of tasks in our modern world.

    • Perfect STEM Gift: Fun and Educational Mega Cyborg Hand Kit!
I bought the Thames & Kosmos Mega Cyborg Hand STEM Experiment Kit as a Christmas gift for my 9-year-old son, and it was a huge hit! From the moment he opened it, he was excited to dive into the building process. The instructions were clear and easy for him to follow, and he managed to assemble it mostly on his own, with just a little guidance. Watching him figure out how each piece fit together and seeing his pride in completing it was priceless. The kit provides a fantastic hands-on learning experience, teaching mechanical concepts and the basics of hydraulics in a fun and engaging way. Once assembled, the cyborg hand is incredibly cool. It fits comfortably, works smoothly, and my son has been having a blast testing its capabilities, like picking up objects or pretending he's a robot. The fact that it’s adjustable for different hand sizes means he’ll be able to use it for a long time. This STEM kit is not only entertaining but also educational, sparking curiosity about engineering and science. I highly recommend it for any kid who loves to build, tinker, and explore how things work. It's a gift that keeps on giving! ... show more

    • Great for a child's thinking process and fun!

    • Good product, most kids will need some help in assembling it. But it works if you get to the end!
Bought this twice - once as a gift for another kid and then again for my son's birthday. It is pretty cool and functional - not really easy to put together. My mechanically-inclined ten-year old was able to figure out most of it on his own, though some sections were a little confusing and it does take a bit of dexterity to get some of the pieces figured out. Instructions are mostly straightforward, but you do really need to ensure you read them correctly (mostly diagrams and numbers, not words). Overall a worthwhile gift - but plan on providing some not insignificant adult supervision to help build it. BTW beware not to accidentally throw away the hydraulic oil! It looks like a dessicant pack, but it is not, and you need it! Finally hand is capable of picking up things like cups of water, etc. ... show more

    • Takes a while to assemble but I enjoyed it.
Fun to build (if you're into models). Works well once assembled.

My 5 year old and 12 year old really enjoyed putting these together. Little tough for my 5 year old but with help of siblings he had a blast.

    • Terrible. 45 yr old dad with failed. (Very educated man)
Very hard to put together and then didn’t work. Child was so disappointed. Was going to order a second one and get an engineer to put together but decided to cut my loses.
