Tharla an chéad taispeántas poiblí de luascadán Foucault i mí Feabhra 1851 san Meridian i Réadlann Phárais. Cúpla seachtain ina dhiaidh sin, rinne Foucault a luascadán is cáiliúla, nuair a chuir sé bob liathróide 28-kg práis brataithe le sreang 67-m-ar fhad ó chruinneachán an Phanthéoin, i bPáras. Bíonn <nowiki>[[Plána (matamaitic)|plána]]</nowiki> an luascadáin ag rothlú deiseal thart ar 11.3 ° san uair, ag déanamh amach ciorcal iomlán i thart ar 31.8 uair an chloig. Aistríodh an bob bunaidh a úsáideadh sa bhliain 1851 ag an Panthéon go dtí an Conservatoire des Arts et Métiers i bPáras. Rinneadh an dara suiteáil sealadach don chomóradh 50 bliain i 1902. <ref>{{cite web|url=http://www.parisenimages.fr/fr/galerie-collections/9232-13-pendule-foucault-du-pantheon-ceremonie-dinauguration-m-chaumie-ministre-linstruction-publique-brulant-fil-retenue-mettre-marche-pendule-1902|title=The Pendulum of Foucault of the Panthéon.
