National Geographic GID Marble Pack 25 Glass Marbles That Glow-in-The-Dark, with Storage Pouch and UV Keychain Light Sets (Multicolour)

This was given as a gift to my niece and nephew. They just adore all the combinations they can make and I love watching how it increases their problem solving skills. This toy is durable and keeps them entertained for long amounts of time with our technology!

Congratulations! You’ve arrived at the Cadillac of marble runs. After buying some other difficult to assemble and component limited competitors, I’ve decided this kit is tons of fun and way better for kids’ attention span.After opening this set up my daughter and I got to work making towers of exciting marble runs.No need for instructions, most pieces you’ll figure out, and then for the pieces that look weird your wife will read the instructions and explain it to you later! The pieces are simple and connect easily, and you’ll fight your children for the “cool” pieces.There are lots of support pieces and several unique pinwheel, looping, spiraling pieces. Some pieces branch in different directions so you can build multipath runs that go in different directions.Yeah some of the connections maybe get a little unstable (there’s actually descent support bases) but we’re talking about building a marble run towers taller than my 6 year old. If it falls and crashes who cares, just rebuild a new one! They’ll only cry temporarily and you can re-acquire the “cool” pieces your kids wouldn’t share after the crash and barter them back for promises of baths and chores.The marbles are glow in the dark. My wife informed me of this on day 2. So build your tower at dusk and then prepare for the spectacular marble light show extravaganza.In all honesty, this is a great set. Lots of pieces, peak interest in creativity, and I especially appreciate there were no published designs. It forced us to be creative and design our own runs.

The Magnetic Marble Run is a 50-piece STEM building set that seamlessly blends fun and education. With magnetic pieces that snap together effortlessly, kids learn about magnetism while constructing dynamic marble runs. The open-ended design fosters creativity and problem-solving skills, and the set's durability ensures lasting play. A standout in quality and educational value, this marble run is a captivating tool for cultivating young minds. My son loves it!

Only sticks on magnetic surfaces that made the areas of play limited. Squeals of delight occurred as marbles tumbled down the fridge door though.

I chose this over cheaper ones that did look very similar and really feel like it was worth the money. I bought the bigger 250 one for my 9 year old's birthday. My 12 year old daughter loves it just as much, so does my husband. Huge hit!
