======Flying Optical Illusion====== **Materials: **{{$demo.materials_description}}\\ **Difficulty: **{{$demo.difficulty_description}}\\ **Safety: **{{$demo.safety_description}}\\ \\ **Categories:** {{$demo.categories}} \\ **Alternative titles:** Floating with Mirrors ====Summary==== {{$demo.summary}} ====Procedure==== - Place a large flat mirror vertically on the floor, with volunteers holding it if needed. - Stand with one leg in front of the mirror and the other leg hidden behind it. - From the audience’s perspective, the leg in front of the mirror appears as the opposite leg reflected. - Lift the leg in front of the mirror. The reflection makes it appear that both legs are raised, creating the illusion of flight. - Ask students to explain how reflection creates this illusion. ====Links==== Flying mirror Illusion - dArtofScience: {{youtube>qq5CtxgP-bc?}}\\ 📄 Flying Optical Illusion - Science World: [[https://www.scienceworld.ca/resource/flying-optical-illusion/]]\\ ====Variations==== * Let student volunteers try the illusion to experience it themselves. * Experiment with arm positions or props to see how reflections change perception. * Use multiple mirrors to create more complex illusions. ====Safety Precautions==== * Handle the mirror carefully to avoid breakage or injury. * Ensure the mirror is stable and supported so it does not tip over. * Clear the demonstration area of tripping hazards. ====Questions to Consider==== * How many actual legs are being seen in the illusion? (Only one real leg plus its reflection.) * Which parts of the legs are visible? (The front leg and the mirror’s reflection of its inner side.) * Why does the brain interpret the reflection as a second leg? (The reflection appears in the orientation expected of the hidden leg.) * How does this demonstration show the properties of light? (Light rays reflect off the mirror and travel to our eyes, creating the illusion of depth.)
