An impossible mathematical magic illusion that will baffle your friends, family, and audience!
✨ The Magic Effect:
Place this 3D-sculpted arrow in front of a mirror:
- In real life, the arrow clearly points to the RIGHT ➡.
- Look at its reflection in the mirror... it points to the LEFT ⬅!
- Rotate the arrow 180 degrees on its turntable stand... it STILL points to the RIGHT in reality and to the LEFT in the mirror!
🔬 How it works:
Based on Professor Kokichi Sugihara’s famous anomalous optical geometry, the 3D contour has precise differential height modulations calibrated for a 45° viewing angle that creates conflicting perspective cues between your direct line of sight and the mirror reflection.
🛠 Printing & Assembly:
- 100% Support-free: Prints cleanly in less than 1 hour.
- Includes a smooth rotating display turntable stand and a mirror holder bracket.
- Recommended layer height: 0.20 mm (or 0.15 mm for smooth curved slopes).
