After advent of Islam especially through and after the reign of Abbasid caliphs; interest of scientists and engineers wasdrawn towards the” mechanical or ingenious devices”. The wise jar was originally designed by Ahmad ibnMüsä, thefamous Iranian scientist who lived in the ۵th century A.H.(۹th A.D). It consists of a jar with a mechanically intelligentmechanism inside, which is capable of separating two liquids on the bases of their densities. This jar was constructedand tested as a part of an experimental archaeology research project at the Iranian Research Organization for Science &Technology (IROST). The jar was designed in detail, and was manufactured and tested according to a book entitled Al-Hiyal; written by Ahmad ibn Müsä. However, to establish the correct operation of the jar, minor modifications were madeto its original design set up and it was tested, and as a result the jar operated as expected by the book.
