Avui dijous 13 de novembre, en No\u00e9 i l’Esteve, professors del Departament de Ci\u00e8ncies, han presentat la p\u00edndola cient\u00edfica a l\u2019alumnat de 4t d\u2019ESO. En aquesta ocasi\u00f3 la p\u00edndola es titulava \u201cFocs artificials”, un viatge en la hist\u00f2ria dels focs lligada al descobriment de la p\u00f3lvora. Tamb\u00e9 s’ha explicat com s’obtenen els colors en els focs i s’han fet petits experiments que hi estaven relacionats com la reacci\u00f3 de combusti\u00f3 del magnesi (aquesta reacci\u00f3 genera una llum blanca molt intensa que els fot\u00f2grafs del segle XIX i principis del XX feien servir com a “flash”), o com les flames del coure i de l’estronci responsables del color verd i vermell dels focs.<\/p>\n
