NATIONAL GEOGRAPHIC Glowing Marble Run – 250 Piece Construction Set with 50 Glow in The Dark Glass Marbles & Storage Bag, STEM Gifts for Boys and Girls, Building Project Toy (Amazon Exclusive)

My 5 year old loves this thing, he can spend hours and hours playing and not get bored. You can build whatever you want and it works just fine.

Pieces fit together very well. Marbles have little confetti inside that glow in the dark after sun exposure. Pretty awesome to shut the lights off and watch the marbles race. Was able to figure out how to use every piece efficiently, which is pretty cool to me. Critical thinking definitely required. Included the photos so my design can be reproduced later. Oh, also of course my 4 year old loves it too lol

Bought this for my recently turned 9 year old daughter. Tried to buy birthday gifts this year that were more STEM driven, as I find they have much more play time and hold attention better. This hit the mark precisely! It’s a lot of fun for her to get creative and build new runs and even discover ways to create trick shots as well.

Fun marble run but a bit difficult to set up for younger kids.

Fantastic, kept my grandson busy for hours

Awesome set. A lot of variation in pieces and lots of them.

My kids enjoyed this

Perfect
