MAT\u00c3\u2030RIEL.
\n4 Pommes de terre
\n4 bouts de fil de cuivre \u00c3\u00a9pais ou 4 pi\u00c3\u00a8ces de monnaie en cuivre
\n4 clous en zinc (clous galvanis\u00c3\u00a9s)
\n4 c\u00c3\u00a2bles avec une pince crocodile \u00c3\u00a0 chaque extr\u00c3\u00a9mit\u00c3\u00a9

Lorsqu’on place les pi\u00c3\u00a8ces en cuivre (p\u00c3\u00b4le positif) et les clous en zinc (p\u00c3\u00b4le n\u00c3\u00a9gatif) dans la pomme de terre, une r\u00c3\u00a9action chimique dans le jus de la pomme de terre produit de l’\u00c3\u00a9lectricit\u00c3\u00a9.<\/p>\n

\u00c3\u2030TAPES.
\n01. Poncer l\u00c3\u00a9g\u00c3\u00a8rement les fils ou les pi\u00c3\u00a8ces de cuivre et les clous en zinc
\n02. Placer un fil ou une pi\u00c3\u00a8ce de cuivre et un clou dans chaque pomme de terre
\n03. \u00c3\u20ac l’aide d’un c\u00c3\u00a2ble, relier la pi\u00c3\u00a8ce de monnaie d’une pomme de terre au clou d’une autre pomme de terre
\n04. Relier les 2 extr\u00c3\u00a9mit\u00c3\u00a9s libres de l’ampoule<\/p>\n

NOTES.
\nLes agrumes (citrons, oranges, pamplemousse) peuvent aussi faire l’affaire, ils ont de bonnes propri\u00c3\u00a9t\u00c3\u00a9s de conductivit\u00c3\u00a9.
\nM\u00c3\u00aame s’il est possible de produire quelques volts d’\u00c3\u00a9lectricit\u00c3\u00a9, cette exp\u00c3\u00a9rience est limit\u00c3\u00a9e dans le temps (l’\u00c3\u00a9lectricit\u00c3\u00a9 produite reste de courte dur\u00c3\u00a9e). Aussi : cette exp\u00c3\u00a9rience rend les pommes de terre impropres \u00c3\u00a0 la consommation.<\/p>\n
