  1. Comencem introduint una petita quantitat d’aigua a l’interior de la llauna. Amb nom\u00e9s un parell de cullerades \u00e9s suficient per al nostre prop\u00f2sit.<\/li>\n
  2. Omplim un recipient amb aigua freda.<\/li>\n
  3. Amb l’ajuda de pinces, agafem la llauna i l’aproximem a la font de calor.<\/li>\n
  4. Mantenim la llauna sobre el foc fins que comenci a bullir i observem com surt vapor pel forat.<\/li>\n
  5. Amb compte, situem la llauna damunt del recipient, assegurant-nos de mantenir-la sempre amb les pinces.<\/li>\n
  6. Amb un moviment r\u00e0pid i prec\u00eds, girem la llauna de manera que la seva obertura quedi en contacte amb l’aigua i la submergim aproximadament uns 2 o 3 cm.<\/li>\n<\/ol>\n

    Per qu\u00e8 passa?<\/p>\n

    En el moment en qu\u00e8 introdu\u00efm la llauna a l’aigua freda, el seu contingut es comprimeix. L’escalfament de la llauna provoca que l’aire a l’interior es dilati, augmentant la pressi\u00f3 interna fins a superar la pressi\u00f3 atmosf\u00e8rica exterior. En traslladar la llauna a l’aigua freda, la temperatura de l’aire a l’interior disminueix r\u00e0pidament, causant la seva contracci\u00f3 i reduint la pressi\u00f3 interna per sota de la pressi\u00f3 atmosf\u00e8rica externa. Aix\u00f2 provoca una implosi\u00f3, fent que la llauna es comprimeixi cap a dins. El resultat \u00e9s una demostraci\u00f3 fascinant dels principis de la f\u00edsica que ens han impressionat molt.<\/p>\n
