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.

My 7 year old son really wanted this toy but building it was a challenge. Luckily his ten year old brother loves to build things and did most of the work. Please note it will take several hours to build so patience is necessary.

Ohhh boy was this fun to build. Built it with my child and he had a blast. It is a more fragile toy though so keep that in mind. The plastic material isn’t super thick so keep that in mind. Some nice tech cutters would’ve helped or maybe even nail trimmers to clip off the nubs. Functions really well with just air in the pistons.

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!

This is absolutely the best gift for our 11-year-old this year. The directions were super clear and easy for him to follow. It took him about five hours in total but there was no missing parts, nothing broken, and everything works exactly as described. We have tried other forms of robot hands before, but they have all had failures. This product was absolutely wonderful. We highly recommend this product!

My son is 6 1/2, and was able to build 85% of this on his own or with very minimal help. We had the special clippers that made snipping out the pieces super easy without having to file down the burs. Her said it was the best present ever. Was great for spending time together and a great learning experience for him.This was all I was hoping it would be and more ☺️

Muy bueno es el juguete. Unico que si nos costo mucho trabajo a armarlo, pero valio la pena, la mano salio super padre, los dedos se mueven y si se puede agarar las cosas. Unico que si, hay que armar super quidodasomente, pero se puede desarmar y armar a nuevo en caso hay un error. Fuimos afuera, y todos niños quedaron bocaabierta.

The product looks amazing with very very detailed instruction inside. However, the box was delivered without wrapping, no Amazon bag, no Amazon box. The box is damaged and does not look like a new one. The shipment sticker was put directly on the box with the product. This is a gift and it took me a while to remove the sticker. Consider another seller of this product.

Purchased for 8yo son, there was no way he could complete this! Husband worked on it for a few hours and still struggled. The concept is very cool and son absolutely loves the finished product but definitely was not age appropriate for assembly

Cool product, I would definitely say needs an adult to help build. Box did not come with mini screw driver, so trying to find the right size to work was a bit difficult. Instructions didn't inform you on what you needed for size. Got half of it built and then when we got to the hydronic part, the instructions did not state what type of pil to use and did not provide it as well. Other than that once we can figure out how to build the rest then this would be a cool hand.

While the parts in the box is all complete, the box is dented and the seal is broken. Meant to be a gift for a little boy. Lesson learnt to buy toys from physical stores in the future
