Thames & Kosmos Roller Coaster Engineering STEM Kit | Design, Build, Experiment w/ Working Roller Coaster Models | Explore Physics, Forces, Motion, Energy, Velocity & More | Solve Building Challenges

Easy to assemble and my kid(5) loves it. The posts come out easily but theyre mass produced plastic parts

My grandson loves this. He recieved it for Christmas.

Bought as a gift and the grandchildren love it ! Very versatile and can change the track for different outcomes ! The package came on time and was not damaged! Great Stem product and awesome product for the engineer in the family! Overall great quality material and would recommend it for purchasing !!

As I tried to illustrate in the pictures, I didn't follow the typical building model. However, my complains are not caused by that. My biggest one is the track system on the "cars", they are not tight enough and tend to wobble around, reminding me of early hot wheels tracks that would create too much bouncing and movement in the structure to be sound and therefore stay together. The only other would be the consistency of the part fittings. Most fit together nicely and stay together, however you do run across those parts with loose fittings here and there which I salt with hot glue. Overall, this is a great product and much fun for kids.

My 8 yr old grandson absolutely loved the process of learning, solving problems and constructing the roller coaster. His interest and focus applied to the process resulted in an outcome that grew him as a critical, imaginative and fact based thinker. Such a wondrous sight.

Grandson loved this gift! He loves roller coasters and wants to grow up to design and build them one day!

My kiddos loved this roller coaster set! Hours and hours of fun and a great value.

It was great. Easy instructions and many paths to build. Would highly recommend

I got this for my 10 year old who developed an interest in bridge building after a school assignment. Some of the string projects needed adult assistance but overall he had fun building the structures and learning some engineering basics.

Good present

Lo use para varias clases de física y mecánica y funcionóexcelente. El modelo es resistente y te permite crear varios modelos. Totalmente útil!

Elementi ben realizzati; tutto corrisponde alle aspettative. Le istruzioni sono in inglese ma le molte illustrazioni sono facilmente comprensibili.

I wasn't sure if this would be too much for a 7 year old but he loves rollercoasters and building so figured we could build with him if needed. The step by step instructions were very helpful and after the first 2 simpler builds that were straight and a hill, my son was able to build this mostly by himself. He tested and manipulated the loops to get it working and then explored putting coins in the carriage to weight it as different positions and weights. It was really good fun and unintentionally educational. The cost was definitely worth it. As he gets older reading the book and the controlled experiments will be great. For now it is fun.
