La setmana passada Fiorella i Marina, a l’optativa de ci\u00e8ncies de 2n d’ESO van dur a terme i van presentar a la resta de companys una reacci\u00f3 qu\u00edmica. Concretament, van elaborar una l\u00e0mpara de lava, aprofitant la difer\u00e8ncia de densitat entre l’aigua i l’oli. En aquesta, les bombolles de di\u00f2xid de carboni que s’alliberen, quan es dissol una pastilla efervescent, ascendeixen cap a la superf\u00edcie arrossegant part de l’aigua acolorida que, uns segons m\u00e9s tard, torna a caure en forma de gota. Aquest efecte es va repetint cont\u00ednuament creant, aix\u00ed, l’efecte de la lava. Un experiment f\u00e0cil de reproduir, senzill i bonic.<\/p>\n\n\n\n
