Esto es lo que llamamos una &#8220;imagen real&#8221;. Al ser esf\u00e9rica, la canica act\u00faa como una &#8220;lente convexa&#8221; de gran potencia. Al concentrar la luz en un solo punto, consigue proyectar la imagen del fluorescente lejano sobre el papel. Es exactamente el mismo principio que utilizan nuestros ojos o las c\u00e1maras para capturar im\u00e1genes.<\/p>\n<h3>Experimento 2: Una lupa para ampliar letras<\/h3>\n<p>Ahora, prueba a pegar la canica directamente sobre las letras de un papel impreso. \u00a1Ver\u00e1s c\u00f3mo se transforma en una lupa al instante!<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-26086 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2016\/10\/2ec0e4914b59a73e7a319cbd5d26a663.jpg\" alt=\"%e3%82%b9%e3%82%af%e3%83%aa%e3%83%bc%e3%83%b3%e3%82%b7%e3%83%a7%e3%83%83%e3%83%88-2016-09-30-9-57-49\" width=\"437\" height=\"415\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2016\/10\/2ec0e4914b59a73e7a319cbd5d26a663.jpg 437w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2016\/10\/2ec0e4914b59a73e7a319cbd5d26a663-300x285.jpg 300w\" sizes=\"auto, (max-width: 437px) 100vw, 437px\" \/><\/p>\n<p>\u00bfQu\u00e9 te parece? \u00a1El car\u00e1cter &#8220;\u5927&#8221; (grande) se ha ampliado unas cuatro veces!

Cuando nos alejamos cierta distancia de la lente (la canica), las trayectorias de la luz se cruzan y la imagen se invierte.<\/p>\n<p>De hecho, la imagen que se proyecta en nuestra retina tambi\u00e9n est\u00e1 invertida originalmente. Es nuestro cerebro el que la corrige instant\u00e1neamente para que veamos el mundo al derecho. \u00a1Es incre\u00edble que con una simple canica podamos experimentar c\u00f3mo funcionan nuestros propios ojos! Cuando les doy una a mis alumnos, todos se quedan fascinados mirando cosas a trav\u00e9s de ella y empiezan a jugar. Creo firmemente que este &#8220;juego&#8221; es la puerta de entrada al inter\u00e9s por la ciencia. Como las canicas son baratas y f\u00e1ciles de conseguir, os animo a probarlo tanto en el aula como en casa.<\/p>\n<h3>Contacto y solicitudes<\/h3>\n<p>\u00a1Acercando la magia y la diversi\u00f3n de la ciencia a todos!
