The first object used as Little Devil is a small jug which Magiotti called caraffina (1648). It is placed inverted, upside-down, and is ballasted with lead wire. He suggested applying pressure with one’s palm. Borelli (1670) and Desaguliers (1744) show a similar drawing.
Kircher (1654) designed a bottle with a narrow neck that allows you to put pressure with your thumb. Other authors have used similar machines, among them Schott (1657), Lana (1686), Sturm (1685) and Leupold (1726), who showed some devices which are akin to the one called Florentine Experiment, a name suggested by Schott.
Dechales (1674) closed the glass bottle with a pig’s bladder which allowed him to put pressure.
