Aquest experiment per observar com desapareix la closca de l’ou l’hem realitzat en dues sessions. Dimecres passat v\u00e0rem posar l’ou dins del got amb vinagre i avui hem comprovat com la closca ha desaparegut i, en el seu lloc, ha quedat nom\u00e9s un tel gaireb\u00e9 transparent que permet que l’ou pugui rebotar i no es trenqui quan cau damunt una superf\u00edcie.<\/p>\n

Despr\u00e9s de debatre qu\u00e8 ha passat, hem tret conclusions de com ha pogut desapar\u00e8ixer la closca dura i de color fosc. El vinagre cont\u00e9 \u00e0cid ac\u00e8tic que, en contacte amb el carbonat de calci de la closca, reacciona i, literalment, se’l menja.<\/p>\n
