Static electricity experiment. Strips of paper have been charged by friction by rubbing them. When held together, as shown, the strips of paper repel each other and fan out as seen. This illustration, part of a section titled 'Experiences de Physique sans Appareils' (illustrating popular physics experiments that don't require the use of laboratory equipment), is from 'Physique Populaire' (Emile Desbeaux, 1891).
