The Ravensburger Gravitrax Starter Set Marble Run & STEM Toy Games sets out to make education fun, and it\u2019s one of the best toys games for the job. With an interactive track system, one with interchangeable pieces, you and your children can create elaborate marble runs while stealthy teaching them concepts such as gravity and kinetic energy.\r\n\r\nWhy We Like It - Ravensburger Gravitrax Starter Set Marble Run & STEM Toys Games\r\nSecretly sharpen your child\u2019s critical thinking skills with an elaborate set of tracks and marbles, capable of being fitted in unique and creative ways.\r\n\r\nPerformance\r\nWhat we found so great about the Ravensburger Gravitrax Starter Set Marble Run & STEM Toy Games is the number of pieces. There\u2019s 122 to mess with, including a cannon. You play the tiles down, use pieces to lock them together, and create pathways for the marble(s) to travel on. This creativity helped teach how gravity and kinetic energy affect speed and trajectory. Since the marbles are metal, magnetic pieces demonstrated how metal and magnets react to one another.\r\n\r\nThe Ravensburger Gravitrax is a great way of sharpening the mind, like the LeapFrog RockIt Twist Handheld Learning Toys Games System. Challenge your child with the objective of reaching a specific area with a limited number of pieces. For something more physical, check out the Elite Outdoor Toys Games For Kids.\r\nDesign\r\nThe board itself is made of a series of hexagons, with each piece fitting perfectly into each one. This makes the board, and its pieces, interchangeable and all kinds of combinations can be made. And if you so choose, you can follow designs that come packaged inside.\r\n\r\nThe pieces themselves are surprisingly durable. Each piece is made of plastic, while the track the marbles follow is made of metal. We\u2019ve seen similar durability from the ThinkFun Laser Maze Toys Games.\r\nValue\r\nWith how fun the Ravensburger Gravitrax Starter Set Marble Run & STEM Toy Games, the number of pieces you get in the original packaging, and the endless possibilities\u2014we find the Ravensburger Gravitrax Starter Set Marble Run & STEM Toy Games to have superb value.\r\n\r\nYou already get 122 pieces to mess with but can expand your track to ridiculous lengths with expansion packs. The kind of learning kids can glean from this toy is great, not unlike the LeapFrog RockIt Twist Handheld Learning Toys Game System.\r\nRavensburger Gravitrax Starter Set Marble Run & STEM Toys Games Wrap Up\r\nThe best STEM toys know how to teach your kids new concepts without boring them, and that\u2019s what the Ravensburger Gravitrax Starter Set Marble Run & STEM Toy Games does best: making learning fun.
