Experience the science of illusion with our advanced Optical Stealth Panel. Utilizing precision-engineered lenticular grating technology, this panel creates stunning visual disappearance effects when used according to these professional guidelines: Maintain a minimum 30cm distance between the panel and subject. For optimal effect, subjects should avoid bright-colored clothing and perform against backgrounds with horizontal patterns (such as stair steps or rolling shutters). Critical alignment requirement: Position the panel's grating lines parallel to the subject's body and perpendicular to background horizontal patterns - precisely at 90 degrees. Follow our demonstration video for exact implementation; no hidden mechanisms or deceptive editing required. Safety notice: The material's corners are sharp - we recommend wearing protective gloves during handling and performance. As an optical-grade instrument, please handle gently to prevent scratches, bends, or damage to the specialized surface. This professional-grade prop is ideal for magicians, theater productions, film special effects, and scientific demonstrations. Each panel comes with detailed alignment instructions and recommended background scenarios for achieving perfect vanishing effects.
