What our testers said

“We can build something amazing with these.” – Girl aged 10

“Shall we make the flextube go from here to here? The ball could build up some speed.” – Boy aged 10 

What our experts think

The six different extensions to the gravity powered track system really further the construction experience, allowing children to build and experiment creatively in different ways. This encourages them to use key STEM skills such as  logical thinking, planning and problem-solving to create a working route for the ball in motion. 

This is also a great way to demonstrate scientific concepts such as gravity, kinetic energy and magnetism. While the children did need some adult help in putting the extensions together, once this was done the set was easy to use and connect. We like the variety these set offers as it means lots of play opportunities – children have room to get creative and this gives the toy itself longevity too.
