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)

We absolutely loved this gift for our 4 year old granddaughter. It was fun for all of us to make different runs with it - she really liked the creativity of it and the flow in the dark marbles. I also purchased more marbles and it's really fun watching so many take different tracks. Only criticism I will give is that it's not super sturdy it good enough and if it does fall , the beauty of it is , you can set it back up or make different one !

We got this for our son's fourth birthday and it's provided endless hours of fun! It's easy enough for him to put together and there are so many great little accessories and fun pieces he can use. 5/5 for sure!

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

The kids (ages 4,6,8) love this marble run! It entertains them for hours and the glow in the dark marbles are so cool. Unfortunately two pieces were flawed, and we already threw away the box. I wish there was a way to get a few replacement pieces than return the whole set!

Are awesome… my husband and toddler loves them also the marbles glow in the dark and the coolest thing is come with the light to make them glow.

My sons love to build incredible structures to run. As a parent my only concern is that the little balls get lost all over the house and with my small of 5 I am concerned he can put them jn his mouth.Otherwise it is a great toy to help them in STEM, develop their imagination and their capacity to understand movement, equilibrium etc. fully recomend it.

*Updated: The more we play, the more frustrating this set is because the pieces like to fall apart very easily if you’re not great at creating a stable creation which results in a frustrated mom and boy. Keep that in mind if you’re child wants to do it independently and is also new to marble runs.That aside, it’s fun. I just wish the small set had more pieces, especially bases to keep it stable to be able to create different designs.*_______So I gave this a 5 star because although it didn’t make me feel like it’s amazing, it’s great for the price and quality.Our son loved it this morning during Christmas. My husband and him built a few drops.Pros: easy to use, marbles are pretty, the light and glow in the dark feature was a hit, and you can achieve a few different drops with the amount you have.Cons:This isn’t the most sturdiest set, seems to be easy to snap if you have an energetic child like ours so be careful, and wish they have come out with an expansion by now.Over all this is fun and the kid loves it!
