Draw a Five-Pointed Star

Science Caravan · Optics

★ Dimensions: Transport dimensions: 540×440×640mm, Display dimensions: 540×440×1450mm. ★ Composition: Consists of ABS plastic molded cabinet, ABS plastic molded pedestal, ABS milky white plastic molded operation tabletop with color silk-screened flip-up instruction board, delay circuit, stainless steel illuminated self-reset metal button, leakage protector, microcontroller-controlled display circuit and alarm circuit, bracket, plane mirror, metal five-pointed star, metal stylus, etc. ★ Scientific Principle: The five-pointed star in the mirror is a virtual image, equal in size to the object but left-right reversed. When drawing a five-pointed star according to the virtual image in the mirror, the direction of hand movement is opposite to the actual direction, resulting in hand-eye incoordination. After repeated practice, the brain gradually adapts to this change. Plane mirrors are widely used in daily life. ★ Operation: Press the "Start" button and hold the stylus; look at the five-pointed star in the mirror and try to draw a five-pointed star on the base plate.
