Draw a pentagram

Exhibition Name

Draw a pentagram

Science Behind It

Draw a pentagram, press the button, hold the paintbrush, look at the image in the mirror, and draw the pentagram on the drawing board, but we often find errors. This is because the pentagram in the mirror is an image formed by a flat mirror, which is the same size as the object and opposite to the left and right. The pentagram pattern is first reflected by a flat mirror and then imaged through the retina, just like the principle of negative being positive. At this point, a normal standing pentagram is formed on the retina. However, according to convention, the brain still habitually flips the received image again and uses it to command the movements of hands and other organs. Therefore, when we draw, the direction of the brush movement will be opposite to the original pattern, deviating from the correct trajectory. It's difficult to draw a pentagram when the hands and eyes are not coordinated.
