Ravensburger GraviTrax Marble Run
I bought this set as a birthday gift for my 8-year-old nephew. It's the perfect gift for a child who likes building things. I like that you can create it 100 different ways so it doesn't get old. It's a great way to have early science discussions about gravity and force while also having fun.
This original marble run toy made with high-quality material provides fun and learning! The Ravensburger GraviTrax Marble Run and STEM Toy features 122 pieces, and the interactive track system of the game allows kids to design their own race tracks. While doing that, they use concepts of gravity, kinetics, and magnetism to propel their ball to the finish. This fantastic toy makes an excellent, screen-free 8th birthday gift.
