Marble Genius is a company that offers a unique combination of STEM learning, action, thrills, and excitement for everyone. Their products are designed to challenge young minds and provide hours of creative, educational fun. One of the main products offered by Marble Genius is the marble run. A marble run is a construction toy consisting of various pieces that allow you to design and build a track for marbles to travel down. The construction process is an engineering challenge that requires problem-solving skills, spatial reasoning, and creativity. With Marble Genius, you can enjoy the excitement of building a marble run and then sit back and watch the marbles roll. One of the great things about Marble Genius is its see-through structural pieces. These pieces allow you to see the marbles in motion as they travel down the track, giving you a better understanding of how the track works and how the marbles move. This visual feedback makes it easier to identify problems and make adjustments to the track as needed. Another great feature of Marble Genius is its free app. The app provides regularly updated content and fresh challenges online, so you can continue to expand your knowledge and creativity as you build more complex tracks. The app also includes tutorials and tips to help you get started and improve your skills. WARNING: CHOKING HAZARD - Small Parts. Not for children under 3 years.
