from the\u00a0<em>Star Wars<\/em>\u00a0saga .<\/p>\n<p>Currently, physics in the cinema is common, but chemistry is camouflaged between images, without significant evidence.\u00a0However, we find examples such as\u00a0<em>Bones<\/em>\u00a0, a well-documented series based on forensic science,\u00a0<em>Breaking Bad<\/em>\u00a0, whose protagonist is a chemistry teacher, and the movie\u00a0<em>Fight Club<\/em>\u00a0, where the manufacture of soap by saponification is detailed.<\/p>\n<p>To adapt the resource to the educational stage, to the time, to the context and to the legislation, we propose to use brief sequences.\u00a0The selection of these is a critical point.\u00a0For 4th ESO Physics and Chemistry, we have selected a fragment from the series\u00a0<a href=\"https:\/\/www.netflix.com\/browse\"><em>Stranger Things<\/em><\/a><\/p>\n<p>The use of film material in secondary education is not as common as in university, although there is enough data to prove its advantages.<\/p>\n<h4><strong>Eleven&#8217;s tank<\/strong><\/h4>\n<p>The scene that we propose takes place from minute 22 to 32 of\u00a0<a href=\"https:\/\/www.netflix.com\/watch\/80077374?trackId=255824129\">chapter 7 of the first season<\/a>\u00a0.\u00a0The protagonists want to generate a portal so that Eleven, the main girl who has extrasensory powers, can contact a friend trapped in a different reality.<\/p>\n<p>Their science teacher explains to them over the phone how to create the right portal: they need to build a\u00a0<a href=\"https:\/\/es.wikipedia.org\/wiki\/Tanque_de_aislamiento_sensorial\">sensory deprivation tank<\/a>\u00a0with a highly concentrated saline solution.\u00a0They prepare the solution by adding common salt until an egg floats.\u00a0Eleven must also float.<\/p>\n<h4><strong>The challenge<\/strong><\/h4>\n<p>The protagonists have 700 kg of salt, which they have to dilute in the volume of water that enters a children&#8217;s pool and at a specific temperature.\u00a0The children place the pool on a basketball court, fill it with water and add salt.\u00a0One checks with an egg if the concentration is sufficient by applying the concept of buoyancy and its relationship with density.<\/p>\n<p>On the first try, the egg sinks.\u00a0In everyday life, this phenomenon is observed when cooking an egg.\u00a0However, after adding more and more salt, he exclaims\u2026 \u201cEureka!\u201d\u00a0The egg floats.<\/p>\n<p>\u201cEureka!\u201d\u00a0is the expression attributed to Archimedes of Syracuse when he discovered that every body immersed in a liquid experiences a vertical and upward thrust equal to the weight of fluid displaced.\u00a0If this push counteracts the weight of an object, the object floats.<\/p>\n<div id=\"attachment_64986\" style=\"width: 690px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" aria-describedby=\"caption-attachment-64986\" class=\"size-full wp-image-64986\" src=\"https:\/\/world.edu\/wp-content\/uploads\/2022\/09\/floatingegg.jpg\" alt=\"\" width=\"680\" height=\"338\" srcset=\"https:\/\/world.edu\/wp-content\/uploads\/2022\/09\/floatingegg.jpg 680w, https:\/\/world.edu\/wp-content\/uploads\/2022\/09\/floatingegg-250x124.jpg 250w\" sizes=\"(max-width: 680px) 100vw, 680px\" \/><p id=\"caption-attachment-64986\" class=\"wp-caption-text\">Dustin, Mike and Lucas check that the egg floats in salt water.
