Dilluns vam posar uns quants ous en vinagre i els hem deixat dins els pots de vidre fins avui. Vam fer unes quantes hip\u00f2tesi del que podria passar i avui ha arribat l’hora de fer comprovacions !!<\/p>\n

Hem observat que el vinagre ja no era transparent i es veia marron\u00f3s. Tamb\u00e9 hem vist que s’havia format com un “moc” marr\u00f3 que surava per la superf\u00edcie. Hem olorat, hem tocat i, finalment, hem colat el vinagre. La cara de sorpresa dels nens i nenes ha estat fascinant.<\/p>\n

La closca havia desaparegut i la consist\u00e8ncia de l’ou era com de “goma” i molt el\u00e0stica. L’hem fet botar, no gaire alt, i rodolar per sobre la taula !!<\/p>\n

EXPLICACI\u00d3 CIENT\u00cdFICA: el carbonat de calci de la closca reacciona amb l’acidesa del vinagre i es produeix una reacci\u00f3 qu\u00edmica que dissol la closca. Tanmateix, el vinagre passa a l’interior de l’ou a trav\u00e9s de la membrana i l’infla lleugerament. Aquest fet d\u00f3na a l’ou una gran elasticitat i aix\u00ed el podem fer botar i rodolar !!<\/p>\n

US ANIMO A FER AQUEST SENZILL EXPERIMENT A CASA AMB ELS VOSTRES FILLS I FILLES !!<\/strong><\/p>\n

ATENCI\u00d3: no el feu botar gaire alt ni l’agafeu gaire fort. Si el voleu fer rodolar suaument, millor a terra !!<\/p>\n
