Mat\u00e9riel : \u00a0– une petite bouteille en plastique<\/p>\n

– sable<\/p>\n

– bicarbonate de soude (7 cuiller\u00e9es)<\/p>\n

– \u00a0un verre de vinaigre<\/p>\n

– \u00a0de la sauce tomate<\/p>\n

– une grande cuvette<\/p>\n

– un entonnoir<\/p>\n

– un verre \u00e0 moiti\u00e9 rempli de semoule<\/p>\n

    \n
  1. Placer une petite \u00a0bouteille \u00a0au centre d’une grande cuvette. \u00a0Former une montagne de sable autour de la bouteille. Ne laisser d\u00e9passer que son goulot.<\/li>\n
  2. Verser la semoule et les 7 cuiller\u00e9es \u00a0de bicarbonate de soude dans la bouteille. Ajouter rapidement \u00a0le m\u00e9lange vinaigre-sauce tomate.<\/li>\n
  3. FIZZZZZ ! \u00c7a cr\u00e9pite dans la bouteille, de la mousse rouge sort du goulot. La mousse coule sur le sable comme de la lave sur la pente d’un volcan.<\/li>\n<\/ol>\n

    Que s’est-il pass\u00e9?<\/p>\n

    Quand le vinaigre entre en contact avec le bicarbonate, il se produit une r\u00e9action chimique. Elle provoque la formation de bulles de gaz carbonique qui s’\u00e9l\u00e8vent brusquement dans la bouteille. Elles entra\u00eenent \u00a0avec elles la semoule et la sauce tomate hors du goulot.<\/p>\n
