Thames & Kosmos - Catapult Engineering STEM Maker Kit, Build 6 Models of Unique Medieval Machines, Explore Mechanical Physics, Includes Safe Foam Balls & Soft-Tipped Projectiles, Suitable for Ages 8+

Son loved it! He’s autistic and this is his current hyper focus! Got it a while back and still plays with it most days!

This is a fun little kit that you probably shouldn't take TOO seriously. It's got the parts for a few different styles of weapon, that are meant to be built one at a time... Basically build one, take it apart, reuse the parts for the next one. If you want multiple weapons built at the same time you're going to need multiple kits. I think it's pretty clear in the description but... best to point it out.Things fit together well, though the instructions could use a once over by someone that knows how to write instructions. Your kids should be able to get through it, but they'll notice it's not as good as something from some of the name brand building block companies.

My daughter loved building her catapult and learning about them in general. We used this as part of her energy unit for science and it was her favorite project of the semester. The directions are great and everything you need is included.

This is a great set for kids who are already very skilled at Lego type building. The instructions are actually not as clear as Lego directions, but if you have an older kid who's confident with building they should be able to handle it. Even though this kit makes multiple options, you can only build one at a time, and they can be difficult to take apart to put back together. The creations work really well though, and it has great educational value.

My son is in the phase of interested in projectile devices. It is fun to build and it’s easy to assemble. This kept him busy for hours and had no problem following the instructions. The built quality is good, he can shoot the projectiles multiple times without falling apart. He likes that it also comes with targets that he can aim at. Overall, excellent kit for hours of fun.
