El dia 18 de maig va venir el pare de l’Emma, en Carles.<\/p>\n

Ens va comen\u00e7ar explicant com s’il\u00b7luminaven els nostres avantpassats quan vivien a les coves. Ens va portar un kit per ensenyar-nos com es feia abans el foc. Va aconseguir que sort\u00eds fum! Vam aprendre que per fer foc es necessitava dues pedres concretes i una era el s\u00edlex.<\/p>\n

Despr\u00e9s ens va ensenyar l’invent de la l\u00e0mpada d’oli. En un got, hi va posar aigua, oli vegetal, una pe\u00e7a de pl\u00e0stic amb un trosset de paper higi\u00e8nic i ho va encendre. I va durar molt! En el passat, feien servir recipients de fang o de bronze per aconseguir aquesta llum.<\/p>\n

M\u00e9s tard, van descobrir la cera de les abelles i en van fer espelmes. Tamb\u00e9 ens va explicar la l\u00e0mpada de gas (llum de carbur) i va portar maquetes per explicar-nos l’electricitat. El cient\u00edfic que va descobrir la bombeta va ser Thomas Alva Edison.<\/p>\n

Per acabar, vam fer un taller on hav\u00edem de fer una espelma amb cera d’abella. Va ser una experi\u00e8ncia xul\u00edssimaaaaaaaaa!<\/p>\n
