80 reviewsGravitrax is awesome! It’s a marble run that you create and it teaches science concepts in a hands on way. You can buy add on kits at major retailers. This base kit is a TON of fun. Great way to teach problem solving and persistence. Can’t recommend it enough. Lots of videos on line where you can get an idea of some of the fun things you can do…
