Seguim amb quatre experiments m\u00e9s que ens van presentar l’Aleix Gim\u00e9nez, la Luc\u00eda, l’Alba i l’Aroa.<\/p>\n

L’Aleix G. ens va fer un truc d’il\u00b7lusions \u00f2ptiques. Va posar una moneda damunt la taula i sobre hi va col\u00b7locar un got sense aigua. Quan va omplir-lo d’aigua, la moneda va “desapar\u00e8ixer”!! Ens va explicar la llei de Snell sobre la refracci\u00f3 de la llum: en incidir un raig de llum sobre un medi diferent a l’aire aquest raig es corba en l’interior de la subst\u00e0ncia degut al canvi de velocitat de la llum.<\/p>\n

La Luc\u00eda va omplir una bossa d’aigua. Quan la va tenir plena la va travessar amb molts llapis. El m\u00e9s sorprenent i que ens va deixar bocabadats va ser que no va caure ni una gota d’aigua. Vam parlar de la for\u00e7a que exerceix el l\u00edquid sobre la superf\u00edcie de l’env\u00e0s on est\u00e0, malgrat hi hagi forats.<\/p>\n

L’Alba va posar un guix blau dins un got d’aigua. Es va desfer, per\u00f2 no va desapar\u00e8ixer com ens pens\u00e0vem. Es va tenyir una mica l’aigua.<\/p>\n

L’\u00faltim el va preparar l’Aroa. Va omplir un plat d’aigua i hi va tirar pebre negre. Despr\u00e9s hi va posar sab\u00f3 l\u00edquid i es repel\u00b7lia en contacte amb la pebre. Feia un efecte \u00f2ptic molt bonic.<\/p>\n

Moltes gr\u00e0cies Aleix G, Luc\u00eda, Alba i Aroa per haver-vos preparat aquests experiments i haver fet que gaud\u00edssim de la ci\u00e8ncia una vegada m\u00e9s.<\/p>\n
