Review on 🔧 NATIONAL GEOGRAPHIC Engineering Construction Operations by Tristan Graham

My 10 year old got these as part of our STEM subscription. She was very excited about it and spent half the day working on it instead of playing with the electronics. The kit includes a small piece of sandpaper which was necessary to lighten some of the connections. She could assemble anything but weapons. She was having so much fun. These are also working models. Each of them really shoots, and targets are included. My 10 and 7 year olds have had a really good time playing with it for the past month. They are very strong with consistent play. Pros: *Actually works *Easy to assemble *Sturdy once assembled Cons: *Cannons were difficult for little fingers
