Abstract

The invention relates to a demonstration device generating visual illusion, which consists of an experiment table, a head fixing device, a cylinder, a 'palm' model, a 'coin' model, two mobile devices and a special guide rail used for the motion of the mobile devices, wherein the head fixing device is fixed at one end of the experiment table; the guide rail is fixed at the other end of the experiment table and is parallel with the head fixing device, and the two mobile devices are arranged on the guide rail and can move along the guide rail freely; the cylinder is fixed on one of the mobile devices; the 'palm' model is fixed on the other mobile device; and the 'coin' model can be adsorbed on the 'palm' model. When the demonstration device is used, the left eye of a user can stare at an object about 5 meters away from the user through the cylinder, the 'palm' model is moved close to the cylinder slowly from the right side, the user can observe that a 'hole' appears on the palm of the 'palm' model; and from the 'hole', the object stared by the user can be seen.

Description

1. Technical field [0001] The invention relates to a demonstration device and a demonstration method for demonstrating optical visual effects, belonging to the technical field of experimental demonstration devices. 2. Background technology [0002] British visual scientist Al Seckel (Al Seckel) reported a "hole in the hand" visual experiment in "The Art Of Optical Illusions". The experiment is to hold a cylinder in front of your eyes, look towards something about 5 meters away (one eye through the cylinder), then raise your free hand in front of the cylinder's eye, and hold the Can see the object through the round hole in the palm, if you put a coin in the center of the palm, you can feel the coin seems to be floating. The above-mentioned research results are very useful in demonstration experiments for college and middle school students, or in science popularization work in popular science publicity and education departments. But on the one hand, the above-mentioned resul...
