Educational Kit: A Cross-Boundary Fusion of Nature and Coding
The core appeal of magnetic cobblestone assembly sculptures lies in building "multi-dimensional learning scenarios." The kit includes two key components: natural cobblestones (3-5cm in diameter, polished with embedded neodymium magnets) and a programmable control base. Each cobblestone contains a 2000-gauss neodymium magnet-strong enough to enable stable 拼接 (supporting up to 10 similar cobblestones) while triggering base sensors via magnetic changes.
Crucially, its open programming interface: the base is compatible with the Arduino open-source platform, allowing kids to use graphical programming (for ages 6-8) or code programming (for ages 9+) to set magnetic sensitivity, light feedback modes (with built-in RGB LEDs), and even link simple mechanical structures. For example, when a specific cobblestone configuration is completed, the base lights up in a corresponding color and plays custom sound effects-seamlessly integrating "shape recognition," "magnetism principles," and "programming logic."
Cognitive Experiments: Significant Boost in Spatial Imagination
A 2023 controlled experiment by Singapore's Ministry of Education validated the kit's educational efficacy. It selected 480 third-grade students (8-9 years old) from 12 primary schools, dividing them into an experimental group (using magnetic cobblestone kits) and a control group (using traditional building blocks). Both groups participated in 40-minute creative construction sessions twice weekly for 3 months.
Results showed: the experimental group's scores in "spatial visualization tests" (e.g., 3D shape rotation recognition, multi-part combination imagination) improved by 35% compared to pre-experiment, significantly higher than the control group's 12%. In "engineering thinking assessments" (e.g., structural stability analysis, problem troubleshooting), the experimental group's excellence rate reached 68%-more than double the control group's 31%. Teacher feedback noted that the irregular shape of natural cobblestones, compared to standard blocks, better inspired children's "unconventional combination" attempts, while the linkage between magnetism and coding made abstract "cause-effect relationships" intuitively understandable.
Safety Certification: A Trusted Choice for Parents and Schools
For children's product safety, the magnetic cobblestone kit passed rigorous testing under EU standard EN71-3 (specific element migration). Test data shows heavy metal (lead, cadmium, mercury, etc.) migration is only 0.002mg/kg-1/10 of the standard limit (0.02mg/kg) and well below international safety thresholds.
Design details also reflect safety: cobblestone edges undergo 1000-grit polishing, with surface roughness Ra <0.8μm to prevent scratches; embedded magnets are fully sealed in epoxy resin, remaining intact after 1000 drop tests (from 1.2m onto wooden floors); the base uses food-grade ABS plastic, heat-resistant up to 80℃, and is directly washable with water. These features make the kit suitable for both family parent-child interaction and school group teaching.
