NATIONAL GEOGRAPHIC Glowing Marble Run – 150 Piece Construction Set with 30 Glow in The Dark Glass Marbles & Storage Bag, STEM Gifts for Boys and Girls, Building Project Toy (Amazon Exclusive)

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.

My kids enjoyed this

As a parent this set is iffy. Kids love it but hard to put together (really gotta push em together) and it’s wobbly…. I tried to make it even but they don’t line up the best if that makes sense. Best if used on carpet. The glow in the dark feature is cool but wish it lasted longer.

Perfect

A gift for grandson. should have gotten the bigger set, it was a hit!

Perfect gift! I would say it's for kids aged 8+, otherwise you'll be putting it together constantly. It's great for older children to use their imaginations to create different setups. Setup instructions are not included.

Good
