Il est facile, en effet, de remplir un vase de grains de plomb; puis, par un orifice ménagé au fond du vase, de les lâcher à point nommé. S'ils tombent sur une membrane tendue, sèche et épaisse, ces grains reproduiront le bruit du tonnerre. Dans les théâtres, pour imiter ce roulement, on vide ainsi des récipients remplis de corps lourds qui , frappant comme ci-dessus contre une peau sèche, épaisse et tendue en tout sens, à l'instar d'un tambour, engendrent le bruit en question.
