From one side you can see a cube floating in the middle of the box. When observed from the other side, however, you can see a different shape.<\/p>\n\n\n\n<p><strong>Components:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Magic box<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"Working-Principle:\">Working Principle:<\/h2>\n\n\n\n<p>The Magic Box contains a mirror dividing it vertically through the diagonal.<\/p>\n\n\n\n<p>It is positioned so that it divides the cube in half, giving the illusion that you can view the full interior of the box when you can only see half of it.<\/p>\n\n\n\n<p>The items that have been placed inside add to the overall experience. On one side, there is a cube attached to the mirror that appears to be floating in mid-air. Combined with light effects strategically placed at the bottom it creates the illusion that the box contains only a full cube floating and perfectly centred in the middle of the box. In fact only half a cube is glued to the mirror, the other half that you observe is a reflection only.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"398\" height=\"515\" src=\"https:\/\/2022.robocupjunior.eu\/rcj\/wp-content\/uploads\/2022\/03\/magic_cube.png\" alt=\"\" class=\"wp-image-482\" srcset=\"https:\/\/2022.robocupjunior.eu\/rcj\/wp-content\/uploads\/2022\/03\/magic_cube.png 398w, https:\/\/2022.robocupjunior.eu\/rcj\/wp-content\/uploads\/2022\/03\/magic_cube-232x300.png 232w\" sizes=\"auto, (max-width: 398px) 100vw, 398px\" \/><\/figure>\n\n\n\n<p>When you switch the viewpoint and observe the inside of the box from the other face you\u2019ll see a pyramid.
