    • Bo\u00eete de conservation des aliments en polystyr\u00e8ne \/ assiette en plastique<\/span><\/li>\n
    • Gobelets (l\u00e9gers, par exemple gobelets en polystyr\u00e8ne, gobelets en plastique)\u00a0<\/span>\u00a0<\/span><\/li>\n
    • Paille\u00a0<\/span>\u00a0<\/span><\/li>\n
    • Colle \/ Colle chaude (facultatif)<\/span><\/li>\n
    • Ciseaux \/ Perceuses\u00a0<\/span>\u00a0<\/span><\/li>\n
    • R\u00e9cipient avec de l\u2019eau\u00a0<\/span>\u00a0<\/span><\/li>\n
    • Baignoire avec eau \/ surface d\u2019eau naturelle\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

      Montage:\u00a0<\/span>\u00a0<\/span><\/h2>\n
        \n
      • Utilisez les ciseaux pour percer un trou du diam\u00e8tre de la paille sur le c\u00f4t\u00e9 de la partie inf\u00e9rieure de la tasse\u00a0<\/span>\u00a0<\/span><\/li>\n
      • Collez la paille dans le trou\u00a0<\/span>\u00a0<\/span><\/li>\n
      • Percez un trou sur le c\u00f4t\u00e9 de la bo\u00eete de conservation des aliments et passez-y la paille\u00a0<\/span>\u00a0<\/span><\/li>\n
      • Collez la paille dans le trou\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

        Ex\u00e9cution:\u00a0<\/span>\u00a0<\/span><\/h2>\n
          \n
        • Mettez le bateau dans la baignoire d\u2019eau\u00a0<\/span>\u00a0<\/span><\/li>\n
        • Remplissez soigneusement la tasse \u00e0 moiti\u00e9 avec de l\u2019eau\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

          Observation:\u00a0<\/span>\u00a0<\/span><\/h2>\n
            \n
          • L\u2019eau s\u2019\u00e9coule de la tasse \u00e0 travers la paille dans la baignoire\u00a0<\/span>\u00a0<\/span><\/li>\n
          • Le bateau acc\u00e9l\u00e8re dans la direction oppos\u00e9e\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

            Explication:\u00a0<\/span>\u00a0<\/span><\/h2>\n
              \n
            • En raison de la pression au fond de la tasse, l\u2019eau qui s\u2019\u00e9coule re\u00e7oit une impulsion, \u00e0 l\u2019envers<\/span><\/li>\n
            • En raison de la conservation de l\u2019\u00e9lan, une impulsion oppos\u00e9e est cr\u00e9\u00e9e sur le bateau, vers l\u2019avant (recul).<\/span><\/li>\n<\/ul>\n

              • Le syst\u00e8me de propulsion fonctionne sur le m\u00eame principe qu\u2019une fus\u00e9e<\/span><\/li>\n<\/ul>\n
