Ens va explicar que, de vegades, barrejant dos productes diferents s&#8217;aconsegueix un resultat molt espectacular i ho vam voler provar.<br \/>\nAl primer experiment vam inflar un globus sense pulmons: vam barrejar un detergent amb boles de paper de plata i el gas que extreia feia inflar el globus.<br \/>\nEl segon experiment va ser un coet!! Vam posar dins d&#8217;una ampolla d&#8217;aigua vinagre i bicarbonat,ho vam tapar, hi vam posar un playmobil astronauta i&#8230; vam veure com volava ben amunt!!<br \/>\nL&#8217;\u00faltima part va treure nitrogen l\u00edquid i ens va dir que estava tant gelat que no ho pod\u00edem tocar sense uns guants especials: est\u00e0 a 196 graus sota zero! Vam congelar una fulla, la vam tocar i la vam poder trencar de seguida; tamb\u00e9 vam agafar un globus inflat, es va desinflar quan es va congelar i despr\u00e9s, al tornar a la temperatura normal, es va tornar a inflar!! Al final vam tirar el nitrogen l\u00edquid al terra, va sortir un munt de vapor i vam poder anar a tocar el fum i la terra gelada.<\/p>\n<p>Ens ho hem passat molt b\u00e9!!<\/p>\n\n<p>Aquests v\u00eddeos mostren com hem fet el coet i com hem tirat el nitrogen l\u00edquid:<\/p>\n<p style=\"text-align: center\"><iframe loading=\"lazy\" src=\"https:\/\/www.youtube.com\/embed\/yZsh3hc68FY\" width=\"560\" height=\"315\" frameborder=\"0\"><\/iframe><\/p>\n<p style=\"text-align: center\"><iframe loading=\"lazy\" src=\"https:\/\/www.youtube.com\/embed\/TgfS3Foot-Q\" width=\"560\" height=\"315\" frameborder=\"0\"><\/iframe><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dilluns 5 de desembre a la classe dels gossos i divendres 9 de desembre a la classe del futbol ens va visitar l&#8217;Alexis, qu\u00edmic de professi\u00f3 i treballador de la UDL.<br \/>\nEns va fer tres experiments que ens van agradar molt!!
