STEM Rainbow Marble Run

Lots of fun and comes with a small booklet to teach kids how the marble works and how to adjust the structure for speed etc. Great ideas too for timing runs. Kiddo loves it and works and connects well without many issues. Lots of marbles for a marble rush. Great quality.

I’m not sure who loves this more my kids or my husband. My 3-year-old literally ask to play with it almost every single night.

This set fits the standard sets if you want to expand it but the glow in the dark marbles are, of course, only visible when they pass through the transparent pieces of this sets. We now have about 500 pieces and the grandsons are having a lot of fun with them. After playing with this set, we got the other glow in the dark set (this one and the largest one) and then added two other smaller ones with it. That was their "big" Christmas present. They always make a "charging station" for the marbles (a flashlight placed underneath one of the sets transparent holders) so the marbles stay charged during play and that's not an issue. Lots of fun. The pieces can be stacked pretty high before the towers become unstable but not as high as I would wish. However, the boys seem to not get frustrated because the pieces go together easily. They're 6, 8 and 10.

I only wish it came with more pieces, they are a little unstable at times, depending on the build - but also we bought it for our 2 year old son, he only uses it supervised.. but, He LOVES It!
The glow marbles are awesome, charging them with the light doesn't last as long but they are cool, and seeing them through the tubing is very exciting for him.

I love EVERYTHING about this toy. Working in early childhood, I've seen a lot of marble mazes. This one has more types of blocks, bases, and wheels. The colors are very bright and see-through, so kids love them vs. the traditional primary color solid blocks. There are more bases and different types of bases, so it's easier for the kids to build a sturdy maze. The box is very solid, looks nice and so is the net bad, so I've kept both. There are A LOT of marbles and they come with a little LED flashlight; you shine the light on the marbles for a few seconds and they glow brightly. Since the maze is see-through, you can actually watch them as they fall through the maze. Such a cool idea and I'm so glad I bought this vs. a traditional maze. I am impressed by the quality of this every time the kids take it out. I will be looking at other National Geographic products because of this purchase; wish this brand was offered in stores more often. Definitely better than expensive early childhood education brands.
