Thread the Needle
★Exhibit Content: Science popularization of the characteristics of plane mirror imaging, hand-eye coordination, and visual reversal principles ★Interaction: Manual interaction ★Operation: Hold the string, observe through the viewing hole, try to thread the string into the hole, and experience the visual reversal and hand-eye incoordination caused by plane mirror imaging. ★Exhibit Description: The exhibit consists of a 30 square tube + 2.0mm cold-rolled sheet baked paint display stand, a 12mm Kelaisi artificial stone countertop, a plane mirror reflection device, a perforated flat plate, a string, an acrylic interactive bracket, etc. When the audience observes through the mirror reflection, the image seen is left-right reversed from the actual position, making it difficult to thread the string into the hole. This provides an intuitive understanding of the characteristics of plane mirror imaging: 'left-right reversed, equal size and equal distance', and allows them to experience the visual reversal challenge of hand-eye coordination. Recommended exhibit for the PopsciCat Exhibit Store. ★Scientific Principle: This exhibit is based on the principle of plane mirror imaging: Plane mirror imaging follows the rule that 'the image is equal in size to the object, left-right reversed, and the distance from the image to the mirror is equal to the distance from the object to the mirror'; The hole in the mirror is a virtual image formed by the plane mirror, which is left-right reversed from the real object. This causes the audience to thread the string in the direction seen in the mirror, but the actual operation direction is completely opposite, resulting in hand-eye incoordination; This principle is widely used in periscopes, dance correction mirrors, and other scenarios. It is a classic optical interactive science exhibit.
