Tout d’abord, le bouton, un levier inter-appui placé à l’horizontale, laisse rouler une bille de grande taille sur un plan incliné composé de plusieurs pentes. Au cours de son trajet, cette bille va heurter une autre bille, plus petite que la première, retenue par un petit muret. La grosse bille restera coincée, et la plus petite bille poursuivra son trajet jusqu’à atteindre un autre levier inter-appui, à la verticale cette fois-ci. Le contact avec le levier va pousser une bille de plomb dans See more
