In the eighteenth century, several models of houses, churches and ships were built to show the effect of lightning strokes and the benefits of lightning conductors. This ship is driven by a clock-work motor and sails with its mast (the top of which is missing) against a conductor of an electrostatic generator. This causes an electric discharge. The shock causes the mast to fall to pieces and the hatch to fall out of place. Sometimes, a bit of gunpowder was placed beneath the hatch, to imitate thunder.
