## 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.

Review: 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!
Review: Challenging but Fun Build! Perfect with Adult Help - We bought the Mega Cyborg Hand for our 7 year old, and it has been such a fun and engaging project for our whole family. Building it together has been a great experience, though I would say a 7 year old definitely needs adult help and guidance for some of the steps. There are certain parts where an adult is required, but that actually made it a really enjoyable hands-on project to work on together. Our 10 year old also loves fiddling with it, which shows how well it spans multiple age ranges. The instructions are very clear and thoughtfully laid out, making the build feel much less intimidating. I especially loved that some pages in the manual include fun comic style stories and interesting facts about the physics behind how the mechanics work, it’s a great educational touch! We have absolutely loved this purchase for the value and are excited to finish building it and start using the hand. Highly recommend for families looking for a meaningful STEM project to do together. Age range: 7+

## Questions & Answers

**Q: Hi, any chance we can get replacement part (F16)?**
A: Either the box or instruction sheet should have a customer service phone number or email address.

**Q: Ease to disassemble and reassemble for a classroom use each year?  Say a class of 20 students...one kit per student?**
A: I wouldn't.  The peices are strong when together but there are a handful of screws that need to keep their place. Once the screw threads "bite" into the plastic once, the strength of the attachment will lose alot of integrity if taken out and returned.  Also, there are some adhesive pads that the "fingers" use for traction/purchase that won't peel off very well.  I'm afraid that the pieces very likely would break if carefully taken apart and reassembled.

I'd go as far as saying that it's likely that you would need to purchase 24 for a class of 20 to insure a surplus of "extra" parts for any that may break during assembly.

Good one time assembly project though.

Thank you for being a teacher. I hold teachers in the same regard as first responders as heroes.

Bigs hugs for you.

**Q: I am missing a P2 screw, this toy was a gift, how do I get a replacement?**
A: I haven't had to contact their support line.........buut, the p2 size screw is pretty common.....if you have any old electronics collecting dust, you can probably salvage one from any old tech laying around.

**Q: A P2 screw is missing, can you send one please?**
A: We are also missing that screw. We're you able to find a replacement for it?
