3. Safety Information
No specific safety warnings are applicable for this product beyond general toy safety guidelines. Ensure small parts (marbles) are kept away from young children to prevent choking hazards. Recommended for ages 10 years and up.
4. Setup
The Magnetic Marble Run is designed for use on any vertical magnetic surface. Popular surfaces include refrigerators, file cabinets, whiteboards, and workbenches. The secure snap-fit connectors ensure easy assembly and disassembly.
- Select a Magnetic Surface: Choose a clean, flat, vertical magnetic surface for optimal adhesion of the magnetic pieces.
- Plan Your Course: Refer to the included Learning Guide for example track designs or unleash your creativity to build a unique maze.
- Assemble Components: Connect track pieces and trick pieces using the snap-fit connectors. Ensure all connections are secure to prevent marbles from falling off.
- Attach to Surface: Place the magnetic connectors onto your chosen surface. The strong magnets will hold the pieces in place.
- Test and Revise: Once a section of your maze is built, perform a test run with a marble. Adjust pieces as needed to ensure smooth marble flow and desired action.

5. Operating Instructions
Once your marble maze is constructed, you can begin playing:
- Launch Marbles: Place a marble at the starting point of your track.
- Utilize Trick Pieces: Engage the various trick pieces such as launchers, wheels, and U-turns to guide the marbles through your custom course.
- Motorized Spiral Lift: For continuous play, place marbles into the motorized spiral lift. It will automatically transport marbles to the top of the track, allowing them to descend again.

6. Building Techniques and Concepts
This STEM building set encourages exploration of scientific principles through hands-on play:
- Gravity and Momentum: Experiment with different heights and angles to control the speed and direction of your marbles.
- Engineering Design: Learn about structural stability and track efficiency by designing mazes that successfully guide marbles from start to finish.
- Problem-Solving: Identify and resolve issues such as marbles getting stuck or falling off the track by adjusting piece placement and configuration.
- Creativity: The modular nature of the set allows for endless unique designs, promoting imaginative construction.
The included Learning Guide provides additional insights into physics and engineering concepts relevant to marble runs.
7. Maintenance
- Cleaning: Wipe pieces with a damp cloth as needed. Avoid harsh chemicals.
- Storage: Use the provided storage bag to keep all components organized and prevent loss when not in use.
- Battery Replacement: If the motorized spiral lift stops functioning, replace its batteries (not included).
8. Troubleshooting
- Marbles getting stuck: Check for sufficient downward slope in all track sections. Ensure connectors are fully seated and not creating obstructions.
- Pieces falling off magnetic surface: Verify the magnetic surface is clean and flat. Ensure the magnetic connectors are properly attached to the track pieces.
- Motorized spiral lift not working: Check if batteries are correctly installed and are fresh. Ensure no marbles are obstructing the lift mechanism.
