The disc of Sabu, the historical artifact, was discovered by the English Egyptologist Walter Brian Emery in 1936.The tomb where the disc was discovered belonged to Sabu, the son of Pharaoh Anedjib. According to the Egyptian custom, the tomb was full of household things: pottery and stone implements, copper pots for hygienic procedures, ox bones, arrows, ivory box and so on. The disc is dated back to c. 3100–3000 B.C.

The disc now is kept in the Cairo Museum (Egypt). There are various ideas about the purpose of the disc of Sabu: 

• it is a vase of lotus shape; 

• it is a dish for ritual or religious purpose; 

• it is a support for a torch.

The experiments performed by   Dr. Gizo Vashakidze have delivered different results. The similar disc used in the experiment revealed an interesting feature – emission of vaporized water, conveniently, quickly and at a distance. The results of the experiment can be found out in details in the work.
