The Marbleocity Mini Skate Park Maker Kit, from Tinkineer, is recommended for ages 9+. Although younger kids may enjoy playing with the marble run, they will have trouble building the set. You will need some quality glue, and toothpicks for glue application. Building of this set will typically take an hour or two. The detailed instructions not only do a great job to help with assembly, but include a fun comic book, explaining the basics of physics. Once assembled, the Mini Skate Park Maker Kit looks cool, and rolls without a hitch. You can load all four marbles and turn the gears for fast-paced marble action. The laser-cut wood looks and feels great, and the marbles move like the most skilled of skateboarders. It's clear that the people at Tinkineer are passionate about what they do, and are invested in the customer's experience, and their physics education. It's a STEM product and is made entirely in the US. Once built, there may not be too much repeat play, but the building process and education alone is worth the cost to enter this Skate Park!
